You know, part of me is skeptical of what research show, especially non-RCTs or RCTs without independent statisticians or supervisions. I think even researchers can be biased - we tweak experimental conditions or statistical parameters to get the results we want. Sometimes we omit data outliers. But in the end, I believe science (even with its limitations) is the best thing we've got to think logically. Anyway, great article btw, I really like this one.
