Religion vs I.Q.

[solidsquid]

So, I took the raw data that was listed on that site and played around with it in SPSS. After using GDP of the countries as a covariate and utilizing the residual from that through linear regression I ran a second regression. The original run with just IQ and the religion scores yielded an Rsquared of 0.52 and once I covaried out GDP from IQ there still appeared the same downward trend as in the original graphs with an Rsquared of 0.28 making the variance change of approximately 0.24. Therefore, while the website is correct in that GDP does seem to play a part it is not a refutation of the results that there is still a significant negative trend between IQ and Religiosity and therefore suggests that a higher IQ is still predictive of a lower religiosity score.
