The answer options
Respondents could "Accept" or "Lean toward" any of the options mentioned in the question. They could also choose one of multiple other responses. These additional possible responses were as follows (with minor variations for non-binary questions):
- Accept both
- Reject both
- Accept an intermediate view
- Accept another alternative
- The question is too unclear to answer
- There is no fact of the matter
- Insufficiently familiar with the issue
A "Skip" answer was given by skipping the question instead of picking an answer in the answer form.

. Answer options were randomized wherever they appeared.
In the Metasurvey, respondents had to estimate what percentages of respondents in the primary target population
would either accept or lean toward any of the main positions mentioned in the Survey. For the question on a priori knowledge, for example (question #1 above), respondents had to assign percentages to the following three sets of responses:
- Accept: yes, Lean toward: yes
- Accept: no, Lean toward: no
- Accept both, Reject both, Accept an intermediate view, Accept another alternative, The question is too unclear to answer, There is no fact of the matter, Insufficiently familiar with the issue, Agnostic/undecided, Other, Skip
Respondents therefore had to specify three percentages for this question.

The philosophers available to choose from for the "which philosophers do you identify with?" question were:
Other philosophers could be selected by entering their names manually.
The listed philosophers were largely based on Brian Leiter's polls
concerning the "most important" philosophers in various historical
eras. We included the top 21 from the all-time list (down to
Berkeley) and the remainder of the top 17 from the last-200-years list
(down to Husserl and Heidegger). Because the resulting list was
all-male, we added Anscombe (the highest-ranked woman on the
Regarding the question on philosophical tradition, the two options available by default were "analytic" and "continental". Respondents could enter other traditions manually. See the demographics page for results.
