@alexwild It's a neat experiment, but the presentation suffers from a classic problem: the results are consistent with an effect, but it's presented as if there is none, because it's not "statistically significant".

Since the CI overlaps zero with a mean 12% citation increase, it likely also overlaps 25% increase in citations. "Tweeting has no noticeable effect" and "Our results are consistent with tweeted papers having 1/4 more citations" are wildly different presentations of the same result.
