The author's correctly identify the limitation that the research does not account for bias subsequent to meeting the email authors, but as others have pointed out, it does not mention the limitation that they did not send out pitches proportional to the real world. This is an incredibly obvious causal explanation, and puts in a bad light the scientific integrity of the authors. Which is a shame, because their actual study is interesting and seems fairly rigorous. I read through the actual paper to see if they mentioned this limitation somewhere, not just the abstract, and could not find it. If someone else managed to spot some small clause buried in those pages, please mention where. On a different note, why are academic papers so unnecessarily long? There was a lot of repetition in this one.
