  People Matching Project

Personality items that correlate within friend pairs based on one party self and observer ratings

The main goal of the people matching project is to develop a personality questionnaire to predict comparability between individuals. The question is, what questions should be on the questionnaire?

The greatest challenge of the People Matching Project is to assemble a bank of questions that can predict friendship/relationship compatibility. The best way is just to look at what questions actual friend pairs are similar on. This poses a challenge though as samples of friend pairs are difficult to recruit. Single individuals are much easier and we can try to get the same information by asking single individuals to rate their friends in addition to themselves.

Using matched questionnaires from pairs of real friends would be ideal, but prohibitively difficult. Such data must be collected in the end for validities sake, but for much of the initial item screening and item pool reduction one party surveys have to be used. Research indicates that this may not introduce to much error, Lee, et. al. (2009) found that the similarities between friends on personality traits was exaggerated when one subject rated both individuals, but that the relative importance of traits was not badly distorted. See the figure below.

Full list of items screened

In total, 598 items were screened using 34,899 volunteers. In the table below you can see the items ordered by the correlation (r) between the respondents ratings of themselves versus their ratings of their friends for that item, and how many respondents that correlation is based on (n).
