This dissertation is a collection of three papers – “Knowing Oneself for Others,” “Stereotype Threat and the Value of Self-Knowledge,” and “Self-Knowledge, Epistemic Work, and Injustice” – in which I address the connections between self-knowledge production and social inequality. I explain, using a variety of contemporary political and cultural examples, that marginalized individuals are more likely to be required to know certain things about themselves than socially privileged individuals, especially about those aspects of their lives and identities which are essential (...) to their being marginalized. I argue that this should make us rethink our basic understanding of epistemic injustice, which is typically thought of as involving the prevention of marginalized individuals from producing knowledge. More specifically, in “Knowing Oneself for Others,” I introduce the notion of “compulsory self-disclosure,” a social phenomenon in which an individual is forced to reveal things about themselves, often in ways that further contribute to their oppression. “Stereotype Threat and the Value of Self-Knowledge” addresses how self-ignorance can actually be desirable for individuals facing stereotype threat, and I argue that treating stereotype threat as an epistemic injustice issue can actually harm rather than help individuals in certain cases. Finally, in “Self-Knowledge, Epistemic Work, and Injustice,” I assess the reasoning behind the assumption that marginalized people are self-ignorant; I argue that we need to appreciate the central role that epistemic work plays in self-knowledge production to understand why the standard assumption about marginalized self-ignorance is misguided. Ultimately, I would have us think of self-knowledge production as not just epistemic work but as work that is often emotionally difficult and even metaphysically transformative – coming to have self-knowledge in certain ways can quite literally change who you are. In light of this, the overarching aim of this work is to argue for there being an inextricable link between an individual’s knowledge of themselves and their social status, as well as to discourage readers from thinking of the production of self-knowledge as inherently desirable or as a wholly epistemic issue.

The discourse marker use of the word like is considered by many to be superfluously sprinkled into talk, a bad habit best avoided. But a comparison of the use of like in successive tellings of stories demonstrates that like can be anticipated in advance and planned into stories. In this way, like is similar to other words and phrases tellers recycle during story telling. The anticipation of like contrasted with the uses of other discourse markers such as oh, you know, (...) and well, which almost never re-occurred in similar locations across tellings. Um and uh did sometimes re-occur; these uses are contrasted with like. Although discourse markers are generally used on the fly to handle various issues that come up in coordinating talk as it unfolds, like can be used as an integral part of the story -a marked contrast to the prevalent idea that likes are speech tics.

To generate empathy in the care of vulnerable older persons requires care providers to reflect critically on their care practices. Ethics education and training must provide them with tools to accomplish such critical reflection. It must also create a pedagogical context in which good care can be taught and cultivated. The care-ethics lab ‘sTimul’ originated in 2008 in Flanders with the stimulation of ethical reflection in care providers and care providers in training as its main goal. Also in 2008, sTimul (...) commenced the organization of empathy sessions as an attempt to achieve this goal by simulation. The empathy session is a practical and fairly straightforward way of working to provoke care providers and care providers in training to engage in ethical reflection. Characteristic of the empathy session in the care-ethics lab is the emphasis on experience as a basis for ethical reflection. (shrink)

Words like well, oh, and you know have long been observed and studied in spontaneous speech. With the proliferation of on-line dialogues, such as instant messaging between friends or back-and-forth postings at websites, there are increasing opportunities to observe them in spontaneous writing. In Experiment 1, the interpretation of discourse markers in on-line debates was compared to proposed functions of those markers identified in other settings. In Experiment 2, the use of discourse markers in spontaneous speech was compared to their (...) uses in spontaneous writing. Results support the conclusion that although they vary in frequency in spoken versus written domains, discourse markers are used similarly across domains, but with particular communicative functions that make them non-interchangeable.

Observing others in conversation is a common format for comprehending language, yet little work has been done to understand dialog comprehension. We tested whether overhearers use addressee backchannels as predictive cues for how to integrate information across speaker turns during comprehension of spontaneously produced collaborative narration. In Experiment 1, words that followed specific backchannels were recognized more slowly than words that followed either generic backchannels or pauses. In Experiment 2, we found that when the turn after the backchannel was a (...) continuation of the narrative, specific backchannels prompted the fastest verification of prior information. When the turn after was an elaboration, they prompted the slowest, indicating that overhearers took specific backchannels as cues to integrate preceding talk with subsequent talk. These findings demonstrate that overhearers capitalize on the predictive relationship between backchannels and the development of speakers’ talk, coordinating information across conversational roles.

We explored the differential impact of auditory information and written contextual information on the recognition of verbal irony in spontaneous speech. Based on relevance theory, we predicted that speakers would provide acoustic disambiguation cues when speaking in situations that lack other sources of information, such as a visual channel. We further predicted that listeners would use this information, in addition to context, when interpreting the utterances. People were presented with spontaneously produced ironic and nonironic utterances from radio talk shows in (...) written or auditory form, with or without written contextual information. When the utterances were read without written contextual information, all utterances were rated as equally ironic. But when they were heard as opposed to read, or when they were presented in irony-biasing contexts, originally ironic utterances were rated as more sarcastic than originally nonironic utterances. This evidence suggests both acoustic and contextual information are used when inferring ironic intent in spontaneous speech, and validates previous manipulations of intonation in studies of irony understanding.

The COVID-19 pandemic has presented a global threat to physical and mental health worldwide. Research has highlighted adverse impacts of COVID-19 on wellbeing but has yet to offer insights as to how wellbeing may be protected. Inspired by developments in wellbeing science and guided by our own theoretical framework, we examined the role of various potentially protective factors in a sample of 138 participants from the United Kingdom. Protective factors included physical activity, tragic optimism, gratitude, social support, and nature connectedness. (...) Initial analysis involved the application of one-sample t-tests, which confirmed that wellbeing in the current sample was significantly lower compared to previous samples. Protective factors were observed to account for up to 50% of variance in wellbeing in a hierarchical linear regression that controlled for a range of sociostructural factors including age, gender, and subjective social status, which impact on wellbeing but lie beyond individual control. Gratitude and tragic optimism emerged as significant contributors to the model. Our results identify key psychological attributes that may be harnessed through various positive psychology strategies to mitigate the adverse impacts of hardship and suffering, consistent with an existential positive psychology of suffering.

There has been little previous scholarship regarding the aims, options and impact of ethics education on residential care‐givers. This manuscript details findings from a pragmatic cluster trial evaluating the impact of three different approaches to ethics education. The focus of the article is on one of the interventions, an immersive simulation experience. The simulation experience required residential care‐givers to assume the profile of elderly care‐recipients for a 24‐hr period. The care‐givers were student nurses. The project was reviewed favourably by a (...) university ethics committee, and participants provided informed consent. Data from six postsimulation experience focus groups were analysed thematically and three themes were identified: the experience of vulnerability, dignity in care and the organisation of care. Findings suggest that the immersive simulation experience had a powerful immediate impact as participants described epiphanous insights relating to their care experiences. It is suggested that reflecting on and recording epiphanous events has the potential to sustain ethical care practices. Further research is required to evaluate the impact of different ethics education interventions in different cultural contexts. Exploration is also required regarding the meaning and significance of care epiphanies, those “most delicate and evanescent of moments,” for the sustainability of ethical care. (shrink)

In order to ward off the global threat of a regress of justification, Brandom argues that some claims in our linguistic practices must be treated as “innocent until proven guilty’, i.e. participants must be treated as prima facie entitled when making them. Examples he gives include claims such as “There have been black dogs” and “I have ten fingers”. Brandom calls this idea “the default and challenge structure of entitlement”. In On Certainty, Wittgenstein argues that there are basic certainties (...) (“hinge propositions” or “hinges”) such as “The world existed long before I was born” or “This is a tree” that cannot be meaningfully doubted because they provide the basic frameworks for our language–games in the first place. The aim of this article is threefold. First, it offers an understanding of Brandom’s philosophical project in the light of Wittgenstein’s On Certainty. Secondly, it shows how Brandom may help to elucidate some of the more mysterious passages in Wittgenstein’s “third masterpiece”. Thirdly, it outlines a sketch of a promising solution to an old philosophical riddle. (shrink)

Backchannel choices affect conversational development. Some backchannels invite interlocutors to continue to the next part of what they are saying and others invite them to elaborate on what they have just said. We tested how communicative modality (audiovisual, audio, text), environmental setting (wholly in-lab, partially in the wild), and conversational goals (on-task, off-task) influenced backchannel usage by participants. We found that backchannel production depends on modality, setting, and goals. For example, we found that specific backchannels played a more prominent role (...) in self-motivated dialogue. Knowledge of how backchannels are used has both theoretical and practical implications. (shrink)

Bilingualism has been identified as a potential cognitive factor linked to delayed onset of dementia as well as boosting executive functions in healthy individuals. However, more recently, this claim has been called into question following several failed replications. It remains unclear whether these contradictory findings reflect how bilingualism is defined between studies, or methodological limitations when measuring the bilingual effect. One key issue is that despite the claims that bilingualism yields general protection to cognitive processes, studies reporting putative bilingual differences (...) are often focused on domain specific experimental paradigms. This study chose a broader approach, by considering the consequences of bilingualism on a wide range of cognitive functions within individuals. We utilised 19 measures of different cognitive functions commonly associated with bilingual effects, to form a “cognitive profile” for 215 non-clinical participants. We recruited Welsh speakers, who as a group of bilinguals were highly homogeneous, as means of isolating the bilingualism criterion. We sought to determine if such analyses would independently classify bilingual/monolingual participant groups based on emergent patterns driven by collected cognitive profiles, such that population differences would emerge. Multiple predictive models were trained to independently recognise the cognitive profiles of bilinguals, older adults and higher education attainment. Despite managing to successfully classify cognitive profiles based on age and education, the model failed to differentiate between bilingual and monolingual cognitive ability at a rate greater than that of chance. Repeated modelling using alternative definitions of bilingualism, and just the older adults, yielded similar results. In all cases then, using our “bottom–up” analytical approach, there was no evidence that bilingualism as a variable indicated differential cognitive performance – as a consequence, we conclude that bilinguals are not cognitively different from their monolingual counterparts, even in older demographics. We suggest that studies that have reported a bilingual advantage could well have confounded other key variables that may be driving reported advantages. We recommend that future research refine the machine learning methods used in this study to further investigate the complex relationship between bilingualism and cognition. (shrink)

In various cultural and religious contexts, from West Asia to Southeast Asia, we come across a number of quite similar creation myths in which a peacock, seated on a cosmic tree, plays a central part. For the Yezidis, a sect of Sufi origins that has moved away from Islam, the Peacock Angel, who is the most glorious of the angels, is the master of the created world. This belief may be related to early Muslim cosmologies involving the Muhammadan Light, (...) which in some narratives had the shape of a peacock and participated in creation. In a different set of myths, the peacock and the Tree of Certainty play a role in Adam and Eve’s fall and expulsion from Paradise. The central myth of the South Indian Hindu cult of the god Murugan also involves a tree and a peacock. The myth is enacted in the annual ritual of Thaipusam, like the Nur Muhammad myth is still enacted annually in the Maulid festival of Cikoang in South Sulawesi. Images of the peacock, originating from South India, have moved across cultural and religious boundaries and have been adopted as representing the different communities’ peacock myths. (shrink)

The importance of the Tree of Life when looked at from its negative side will give the reader new perspective of the spiritual path. Ignorance of universal law can mean that when you think you are doing "good", you may actually be doing "evil". Consciousness is the key. This is an important book for students on any path.

"Knowing how we know" is the subject of this book. Its authors present a new view of cognition that has important social and ethical implications, for, they assert, the only world we humans can have is the one we create together through the actions of our coexistence.

Abstract: Biology continues to use the Tree of Life image to show the temporal continuity and discontinuity of the living beings. Moreover, the development of genetic, molecular biology and paleontology has originated phylogenetics. This discipline studies evolutionary relatedness among various groups of organisms through molecular sequencing data and morphological data matrices. The Tree offers interesting points for semiotic perspectives and for theological approaches too. The symbolic reading of the Tree of Life, on the one hand, and the (...) analogies with the Biblical genealogies and some Christian images, on the other hand, will be explored. -/- . (shrink)

The canonical view of a 3‐domain (3D) tree of life was recently challenged by the discovery of Asgardarchaeota encoding eukaryote signature proteins (ESPs), which were treated as missing links of a 2‐domain (2D) tree. Here we revisit the debate. We discuss methodological limitations of building trees with alignment‐dependent approaches, which often fail to satisfactorily address the problem of ‘‘gaps.’’ In addition, most phylogenies are reconstructed unrooted, neglecting the power of direct rooting methods. Alignment‐free methodologies lift most difficulties but (...) require employing realistic evolutionary models. We argue that the discoveries of Asgards and ESPs, by themselves, do not rule out the 3D tree, which is strongly supported by comparative and evolutionary genomic analyses and vast genomic and biochemical superkingdom distinctions. Given uncertainties of retrodiction and interpretation difficulties, we conclude that the 3D view has not been falsified but instead has been strengthened by genomic analyses. In turn, the objections to the 2D model have not been lifted. The debate remains open. Also see the video abstract here: https://youtu.be/-6TBN0bubI8. (shrink)

This paper delves into the intricate connections between the Abrahamic religions and the ancient mystery cults, reaching as far back as to Neolithic shamanism. They all unite in a shared pursuit: the quest for divine knowledge. Long before the Tree of Knowledge of Good and Evil in the biblical Genesis took on its profound symbolic meaning, shamanic initiation held a distinctly different view of botany. Indeed, It regarded plants primarily for their psychedelic properties, as a medium to perceive “reality” (...) with heightened intensity. However, the sacred Tree has a uniquely numinous character, and their consumption is sternly prohibited by God, in both, the Bible and the Quran. Therefore, this effectively positions all monotheistic religions in an unequivocal distance from their prehistoric origins. More precisely, we can argue that these mythologies are in fact constructed as counternarratives, advocating, primarily for a social ethic (based on the holy writings of the Bible), and evoking secondly a fundamental gnostic quest.

"The Natural System" is the name given to the underlying arrangement present in the diversity of life. Unlike a classification, which is made up of classes and members, a system or arrangement is an integrated whole made up of connected parts. In the pre-evolutionary period a variety of forms were proposed for the Natural System, including maps, circles, stars, and abstract multidimensional objects. The trees sketched by Darwin in the 1830s should probably be considered the first genuine evolutionary diagrams of (...) the Natural System—the first genuine evolutionary trees. Darwin refined his image of the Natural System in the well-known evolutionary tree published in the Origin of Species, where he also carefully distinguished between arrangements and classifications. Following the publication of the Origin, there was a great burst of evolutionary tree building, but interest in trees declined substantially after 1900, only to be revived in recent years with the development of cladistic analysis. ¶ While evolutionary trees are modern diagrams of the Natural System, they are at the same time instances of another broad class of diagrams that may be called "trees of history": branching diagrams of genealogical descent and change. During the same years that Darwin was sketching his first evolutionary trees, the earliest examples of two other trees of history also appeared: the first trees of language evolution and of manuscript genealogy. Though these were apparently independent of evolutionary trees in their origin, the similarities among all these trees of history, and among the historical processes that underlie them, were soon recognized. Darwin compared biological evolution and language evolution several times in the Origin of Species, and both Ernst Haeckel and the linguist August Schleicher made similar comparisons. Both linguists and stemmaticists (students of manuscript descent) understood the principle of apomorphy—the principle that only shared innovations provide evidence of common ancestry—more clearly than did systematists, and if there had been more cross-fertilization among these fields the cladistic revolution in systematics might well have taken place in the nineteenth century. ¶ Although historical linguists and stemmaticists have in some respects had sounder theory than have systematists, at least until recently, they have also had the practical problem of very large amounts of data, a problem not often faced by systematists until the advent of molecular sequencing. The opportunity now exists for systematists to contribute to the theory and practice of linguistics and stemmatics, their sister disciplines in historical reconstruction, through application of our commonly used computer programs for tree estimation. Preliminary results from the application of numerical cladistic analysis to a large stemmatic data set have been very encouraging, and have already generated much discussion in the stemmatics community.

Makkai [10] produced an arithmetical structure of Scott rank $\omega _{1}^{\mathit{CK}}$. In [9]. Makkai's example is made computable. Here we show that there are computable trees of Scott rank $\omega _{1}^{\mathit{CK}}$. We introduce a notion of "rank homogeneity". In rank homogeneous trees, orbits of tuples can be understood relatively easily. By using these trees, we avoid the need to pass to the more complicated "group trees" of [10] and [9]. Using the same kind of trees, we obtain one of rank (...) $\omega _{1}^{\mathit{CK}}$ that is "strongly computably approximable". We also develop some technology that may yield further results of this kind. (shrink)

138 titles across a wide range of scholarly publications illustrate the conceptual affinities that connect the palaetiological sciences of biological systematics, historical linguistics, and stemmatics. These three fields all have as their central objective the reconstruction of evolutionary "trees of history" that depict phylogenetic patterns of descent with modification among species, languages, and manuscripts. All three fields flourished in the nineteenth century, underwent parallel periods of quiescence in the early twentieth century, and in recent decades have seen widespread parallel revivals. (...)

The Tree of Nature represents an IT-based approach to understanding Nature in the light of present-day scientific knowledge. The universe, in this view, consists of discrete entities; these are not material particles, however, but information processing events that produce observable changes in the world. The surprising result of this analysis is that the workings of Nature are based on a decision tree consisting of two dozen parameters. The tree is similar to the evolutionary phylogenetic system of the (...) various forms of life, but it is far more fundamental; constituting, as it does, the very base of everything that exists. The overall conclusion is that the universe is steadily producing new information. Metaphorically speaking, it constitutes a self-unfolding story in which events do not pass away into non-existence but instead remain forever as an indelible part of the whole. This also holds true for integrated sets of events, such as the lifetime experiences of an individual. The Tree of Nature leads to the following testable prediction: A successful quantum-gravity theory will involve the notion of a strong complementarity between gravity and the strong nuclear force.

As a way forward in assessing how the Old Testament wisdom tradition might speak to decisions in a modern medical context, in this paper, I propose exploring the iconographic function of the “tree of life” in the Old Testament, which is consistently associated with both wisdom as well as life and health, in order to tease out two-related issues that can help in providing a Christian theological framework for thinking about the problem of the medicalization of risk: first, how (...) should the natural and good human desire for health and long life be framed in terms of the pursuit of wisdom? And, second, how might a sapientially formed character approach risk and uncertainty in making medical decisions? The answers to these questions help establish a framework in which more specific questions related to the medicalization of risk can be assessed. As such, this paper is deliberately programmatic and perspectival rather than prescriptive. (shrink)

This paper discusses a krater recently discovered in a cultic building at Tel Burna in the Shephelah. Of special interest is the krater’s relatively well-preserved decoration containing multiple nature scenes related to the so-called tree of life or sacred tree motif.

Viewing education through the prism of the Torah, Tree of Life, Tree of Knowledge takes the reader through the stages of learning, growth, and self-development that characterize human lives. The journey begins with education as it happens in the home, moves on to the institutions of society, especially schools, and then on to the questions of identity and commitment which constitute the hidden agenda of “informal educational networks.” The self-education of the individual is explored: When does one “grow (...) up”? What is really worth knowing? How does one cope with memories, illness, and anticipations of what lies ahead? This book examines some of the millennial conversation in an attempt to discover an educational philosophy in the Torah that can be relevant to life in the contemporary world. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 27.2 (2003) 255-268 [Access article in PDF] The Tree of Knowledge and Darwinian Literary Study Jonathan Gottscha I THE BRANCHES OF KNOWLEDGE are not strewn randomly on the ground; they are part of a coherent, interconnected tree. Physics is the most fundamental of all the sciences, so it is the trunk of the tree. The branch of chemistry emerges from physics, because the (...) laws of chemistry depend on the laws of physics: chemical reactions occur the way they do because of the physical properties of atoms. Biology's branch splits off from chemistry's: the molecules that comprise living things are bound by the rules of chemistry. Scientists, while grasping this fundamental interconnection of the broad boughs of the natural sciences, 1 have rarely craned their necks sufficiently to glimpse the upper reaches of the tree of knowledge: the green canopy of human culture that is the traditional jurisdiction of the social sciences and humanities. In fact, scholars from all disciplines have mostly proceeded as though the greenery above was the outgrowth of a neighboring tree from a fundamentally different species.Since the 1960s, however, a maverick band of Darwinian neck-craners have been demonstrating that the stuff of human culture, studied in the humanities and social sciences, is a contiguous part of the tree of knowledge: human culture and behavior grow out of human biology. 2 These scholars and scientists continue to define themselves by different names depending on subtleties in their particular approaches: Darwinian psychology, sociobiology, Darwinian anthropology, biosociology, human behavioral ecology, human ethology, and evolutionary psychology. 3 However, sacrificing some precision on the alter of clarity, I will refer to all of the above approaches with the umbrella term of human [End Page 255] behavioral biology, understood in its most expansive sense as the study of how millions of years of evolution shaped the human mind, and thus human behavior, and thus human culture. No matter how human behavioral biologists define their work, they all share the conviction that human behavior, psychology, and culture cannot be fully understood separate from human bio-evolutionary history.Darwinian excavation of the foundations of human nature has inspired a revolutionary movement in the social sciences that proceeds to this day. Like most revolutions, this one has seen its share of rolling heads and intellectual bloodshed. Starting with the "sociobiology debates" of the late 1970s through mid-80s and continuing through the "science wars" of the early-mid 1990s allegations and recriminations of the most serious sort have been almost casually poured into the air: racism, sexism, Social Darwinism, biological determinism, disciplinary colonialism, disciplinary xenophobia, and "biophobia." 4 However, despite entrenched, sometimes zealous opposition, evolutionary thinking has firmly established itself in the social sciences. Thumbing through leading social science journals, it is no longer a shock to encounter articles exploring traditional topics with shiny new Darwinian tools. This stands in stark contrast to the situation in the decades immediately following World War II, where applying biology to human behavior and culture was virtually taboo. In fact, the UNESCO statement of 1952 explicitly tabooed human behavioral biology as scientifically and politically incorrect. Moreover, this phenomenon is in marked contrast to the mainstream social science of the late 1970s and early 1980s, which was in the midst of a wicked backlash against the resurgence of biological inquiry into behavior represented in sociobiology.Currently, while human behavioral biology retains many social scientist critics, and while certain social science fields remain largely hostile or indifferent, invoking biology to explain social behavior is moving toward the mainstream. Almost thirty years after E. O. Wilson made, in Sociobiology (1975), his first call for a merger of disciplines under a new biological synthesis, biology-savvy social scientists and social-science-savvy biologists have provided startling new insights into a host of topics traditionally examined in isolation from biology: gender differences, criteria for mate choice, resource acquisition and allocation, aggression, cooperation, xenophobia, ethnocentrism, sexual politics, religious sensibilities, social hierarchy, moral codes, etc. 5Though one must be careful not to overstate the progress, we are [End Page 256] witnessing...

Our main result is that there exist structures which cannot be computably recovered from their tree of tuples. This implies that there are structures with no computable copies which nevertheless cannot code any information in a natural/functorial way.

The ‘Tree of Life’ is intended to represent the pattern of evolutionary processes that result in bifurcating species lineages. Often justified in reference to Darwin’s discussions of trees, the Tree of Life has run up against numerous challenges especially in regard to prokaryote evolution. This special issue examines scientific, historical and philosophical aspects of debates about the Tree of Life, with the aim of turning these criticisms towards a reconstruction of prokaryote phylogeny and even some aspects of (...) the standard evolutionary understanding of eukaryotes. These discussions have arisen out of a multidisciplinary collaboration of people with an interest in the Tree of Life, and we suggest that this sort of focused engagement enables a practical understanding of the relationships between biology, philosophy and history.

Common ancestry is one of the pillars of Darwin’s theory of evolution. Today, the Tree of Life, which represents how all life is genealogically related, is often thought of as an essential component in the foundations of biological systematics and so therefore of evolutionary theory – and perhaps all of biology itself. It is an iconic representation in biology and even penetrates into popular culture.

[Time, the fundamental dimension of our existence, has fascinated artists, philosophers, and scientists of every culture and every century. All of us can remember a moment as a child when time became a personal reality, when we realized what a "year" was, or asked ourselves when "now" happened. Common sense says time moves forward, never backward, from cradle to grave. Nevertheless, Einstein said that time is an illusion. Nature's laws, as he and Newton defined them, describe a timeless, deterministic universe (...) within which we can make predictions with complete certainty. In effect, these great physicists contended that time is reversible and thus meaningless. (shrink)

This pioneering study interprets the mythology of dualism from Gnosticism to the medieval Cathars to modern nihilism. Couliano shows that, far from being "historically" transmitted, the underlying connection between all dualistic worldviews is a perennial and immensely appealing mindset.

In a recent paper,(1) palaeontologist Mike Benton claimed that our ability to reconstruct accurately the tree of Life may not have improved significantly over the last 100 years. This implies that the cladistic and molecular revolutions may have promulgated as much bad “black box” science as rigorous investigation. Benton's assessment was based on the extent to which cladograms (typically constructed with reference only to distributions of character states) convey the same narrative as the geochronological ages of fossil taxa (an (...) independent data set). Fossil record quality varies greatly between major clades, and the palaeontological dating “yardstick” may be more appropriate for some groups than others.
