Materials and methods

Data

This code gets the files and makes them publicly available.

token:

+ Show code

Use this code in statistical software R to download the data for further use:

install.packages("OpasnetUtils") # You need this line only if you haven't installed this package yet.
library(OpasnetUtils)
objects.latest("Op_en7839", code_name="publishdata") # This line downloads data.frames with the data

Human evolution report survey1 is a report that shows all questions in the survey and simple histograms or frequencies for each question.

Calculations

Preprocess for Dryad data

The Dryad data does not contain objects melted_survey nor critique. They can be calculated from survey1 using this code. Note! This code does not fetch anything, so it only works on your own computer if you have already downloaded object survey1.

AAH criticism and anova

  • Model run 8.9.2017 with all analyses [2]

The code contins the following parts in this order:

  • Anova and Tukey's test
  • Support and rejection of AAH in literature
  • Number of credible hypotheses per trait (individual respondent's view)
  • Explanations for not finding any hypothesis likely
  • Means, SD, and support distributions for all hypotheses ~ Expertise
  • Support distribution for all AAH critiques
  • Credibility of the two most likely hypothesis on the respondent level
  • Support distribution for the most and second moset likely hypotheses
  • Mean and SD of average indices by different determinants
  • Distribution of credibility scores by Expertise
  • AAH criticism
  • Hypothesis conflicts (based on the t2b conflict tables)
  • Number of credible hypotheses
  • Attitudes observed in the literature
  • PCoA of criticism
  • Criticism in AAH familiarity subgroups
  • Mean and SD of individual hypotheses by different determinants

This is the code used to draw the final images. Does not work well in Opasnet at all, but can be copied directly to R.
