Scott Alexander reports on weak correlations and inconclusive results from the latest SSC survey on optical illusions and visual perception. Longer summary

Scott Alexander discusses the results of the latest SSC survey, focusing on optical illusions and visual riddles. He admits to being unable to expand on or strengthen his previous findings from 'Why Are Transgender People Immune To Optical Illusions' and 'Can We Link Perception And Cognition?'. While he weakly replicated some previous results, the correlations were too low to be exciting. He found minimal internal structure in the results, with different versions of the same illusion showing low correlation. The post also briefly mentions some pre-registered investigations that yielded uninteresting or negative results, including studies on political conflict theory, autism and categorization responses, and ADHD and ambition.
