Publication bias<\/a> as normally considered is really positive <\/em>publication bias, i.e., the bias is away from zero, towards finding larger than reality results.

This pattern results from researchers’ own biases towards having something noteworthy to report, wanting to publish it, and getting through peer and editorial review. All of these things are related to political ideology of the researchers and their academic environment (self-censorship). Thus, due to the massive political ideology skew in social science<\/a>, we expect:<\/p>\n
