  1. Failure to Detect Mismatches Between Intention and Outcome in a Simple Decision Task.Petter Johansson, Lars Hall, Sverker Sikstrom & Andreas Olsson - 2005 - Science 310 (5745):116-119.
    A fundamental assumption of theories of decision-making is that we detect mismatches between intention and outcome, adjust our behavior in the face of error, and adapt to changing circumstances. Is this always the case? We investigated the relation between intention, choice, and introspection. Participants made choices between presented face pairs on the basis of attractiveness, while we covertly manipulated the relationship between choice and outcome that they experienced. Participants failed to notice conspicuous mismatches between their intended choice and the outcome (...)

  2. Lifting the Veil of Morality: Choice Blindness and Attitude Reversals on a Self-Transforming Survey.Lars Hall, Petter Johansson & Thomas Strandberg - 2012 - PLoS ONE 7 (9):e45457. doi:10.1371/journal.pone.
    Every day, thousands of polls, surveys, and rating scales are employed to elicit the attitudes of humankind. Given the ubiquitous use of these instruments, it seems we ought to have firm answers to what is measured by them, but unfortunately we do not. To help remedy this situation, we present a novel approach to investigate the nature of attitudes. We created a self-transforming paper survey of moral opinions, covering both foundational principles, and current dilemmas hotly debated in the media. This (...)

    The Selective Laziness of Reasoning.Emmanuel Trouche, Petter Johansson, Lars Hall & Hugo Mercier - 2015 - Cognitive Science 40 (8):2122-2136.
    Reasoning research suggests that people use more stringent criteria when they evaluate others' arguments than when they produce arguments themselves. To demonstrate this “selective laziness,” we used a choice blindness manipulation. In two experiments, participants had to produce a series of arguments in response to reasoning problems, and they were then asked to evaluate other people's arguments about the same problems. Unknown to the participants, in one of the trials, they were presented with their own argument as if it was (...)

    How Something Can Be Said About Telling More Than We Can Know: On Choice Blindness and Introspection.Petter Johansson, Lars Hall, Sverker Sikström, Betty Tärning & Andreas Lind - 2006 - Consciousness and Cognition 15 (4):673-692.
    The legacy of Nisbett and Wilson’s classic article, Telling More Than We Can Know: Verbal Reports on Mental Processes , is mixed. It is perhaps the most cited article in the recent history of consciousness studies, yet no empirical research program currently exists that continues the work presented in the article. To remedy this, we have introduced an experimental paradigm we call choice blindness [Johansson, P., Hall, L., Sikström, S., & Olsson, A. . Failure to detect mismatches between intention and (...)

  6. How the Polls Can Be Both Spot On and Dead Wrong: Using Choice Blindness to Shift Political Attitudes and Voter Intentions.Lars Hall, Thomas Strandberg, Philip Pärnamets, Andreas Lind, Betty Tärning & Petter Johansson - 2013 - PLoS ONE 8 (4):e60554. doi:10.1371/journal.pone.
    Political candidates often believe they must focus their campaign efforts on a small number of swing voters open for ideological change. Based on the wisdom of opinion polls, this might seem like a good idea. But do most voters really hold their political attitudes so firmly that they are unreceptive to persuasion? We tested this premise during the most recent general election in Sweden, in which a left- and a right-wing coalition were locked in a close race. We asked our (...)

    Choice Blindness: The Incongruence of Intention, Action and Introspection.Petter Johansson - unknown
    This thesis is an empirical and theoretical exploration of the surprising finding that people often may fail to notice dramatic mismatches between what they want and what they get, a phenomenon my collaborators and I have named choice blindness. The thesis consists of four co-authored papers, dealing with different aspects of the phenomenon. Paper one presents an initial set of studies using a computerised choice procedure, and discusses the relation of choice blindness to the parent phenomenon of change blindness. Paper (...)

    Choice Blindness and the Non-Unitary Nature of the Human Mind.Petter Johansson, Lars Hall & Peter Gärdenfors - 2011 - Behavioral and Brain Sciences 34 (1):28-29.
    Experiments on choice blindness support von Hippel & Trivers's (VH&T's) conception of the mind as fundamentally divided, but they also highlight a problem for VH&T's idea of non-conscious self-deception: If I try to trick you into believing that I have a certain preference, and the best way is to also trick myself, I might actually end up having that preference, at all levels of processing.

    Letting Rationalizations Out of the Box.Philip Pärnamets, Petter Johansson & Lars Hall - 2020 - Behavioral and Brain Sciences 43.
    We are very happy that someone has finally tried to make sense of rationalization. But we are worried about the representational structure assumed by Cushman, particularly the “boxology” belief-desire model depicting the rational planner, and it seems to us he fails to accommodate many of the interpersonal aspects of representational exchange.

    The Phenomenology of Eye Movement Intentions and Their Disruption in Goal-Directed Actions.Maximilian Roszko, Lars Hall, Petter Johansson & Philip Pärnamets - 2018 - In Timothy M. Rogers, Marina Rau, Jerry Zhu & Chuck Kalish (eds.), Proceedings of the 40th Annual Conference of the Cognitive Science Society. Cognitive Science Society. pp. 973-978.
    The role of intentions in motor planning is heavily weighted in classical psychological theories, but their role in generating eye movements, and our awareness of these oculomotor intentions, has not been investigated explicitly. In this study, the extent to which we monitor oculomotor intentions, i.e. the intentions to shift one’s gaze towards a specific location, and whether they can be expressed in conscious experience, is investigated. A forced-choice decision task was developed where a pair of faces moved systematically across a (...)
