The two attached datafiles correspond to the manuscript "Greener Than Thou: People Who Protect the Environment are More Cooperative, Compete to Be Environmental, and Benefit from Reputation". There are four studies: one datafile for two online surveys with a Prisoner's Dilemma on Amazon Mechanical Turk (Studies 1-2) and another datafile for two in-lab Prisoner's Dilemma experiments with surveys at the end (Studies 3-4). The descriptions of the variables are in separate worksheets within each Excel file. The abstract for the paper is as follows: Abstract: Protecting the environment is a social dilemma: environmental protection benefits everyone but is individually costly. We propose that protecting the environment functions as a signal of one’s willingness to cooperate with others, and test several novel predictions from this hypothesis. We used a mathematical model to show that environmentalism can signal one’s cooperation because it indicates one’s valuation of others. We found support for this prediction in two online studies, and then conducted two laboratory studies to extend the idea that environmentalism signals one’s willingness to cooperate. Participants donated more to an environmental charity when donations were public than when anonymous, but they donated the most when competing to be chosen by an observer for a subsequent cooperative game. In other words, people competed to donate more to the environment. Bigger donors benefited, as they were subsequently chosen more often and received more cooperation from their partners. Partners benefited from choosing environmental donors: bigger donors cooperated more with subsequent partners, such that environmental donations were reliably informative about participants’ future cooperativeness. We compare multiple theories about why people behave environmentally (indirect reciprocity, signal of wealth, signal of cooperative intent), and find most support for our proposed theory that environmentalism functions to signal one’s cooperative intent. By understanding the function of environmental behaviour and stimulating competitive giving, we can increase people’s support for environmental and other charitable causes.

This file contains the coded data for Study 1.

Data for "The association between walkability and personality: Evidence from a large socioecological study in Japan".

This dataset contains all correlations used to compute the meta-analysis.

Data are shared in csv-format and consist of 26 columns and 597 rows (with headings). First column represents the index. Column “last page” indicates on which page the participant closed the survey. As in total there were 7 pages, only those participants with last page = 7 were included for the analysis. (n = 549) Column “control” describes the control question, where control = 1 was the correct answer. All other questionnaires were omitted. (n = 499) The next twenty columns indicate the ten knowledge questions + corresponding confidence levels. Knowledge questions can be incorrect (0) or correct (1). Confidence can range between 50 and 100 in decadal steps. “gender” is binary coded, female (0), male (1), not defined/no answer (NA) “age” is a metric variable, ranging from 18 to 72. “matura” is binary coded, without matura/high school degree (0), with matura/high school degree (1), not defined/no answer (NA) Not relevant data columns for this analysis were removed. Some variables have been recoded or were calculated from other variables. Data were collected in cooperation with market research agency Norstat Deutschland GmbH.

This data was used for a review and meta-analysis on personal space in human-robot interaction by the contributors of this data. Some of the information had to be gained from email contact or estimated from figures and text of the source article.
