I haven't found this to be the case. I check both regularly and much of the "science" that has engagement on Bluesky is thinly-veiled political slop earning engagement as a form of tacit "resistance". It's paper thin (and even the comments here on HN demonstrate a bit of this effect).

X downranks links in general, unfortunately, so unless the research is reformatted for X (rare) it won't get much engagement.
