"easy to replicate (no fancy equipment needed, just ask some people to proofread)"

? This was a human subject study, that would cost $$ and there would be very little upside to confirmation and only a little notoriety with a failure to replicate (which by the way is not dispositive, people might need multiple failed replications to know who to believe, depending on the size of the replication). Maybe you didn't read the post: this was data fraud discovered by statistical irregularities. That is indeed becoming easy to spot with more widespread statistical literacy, at least for unsophisticated jobs like this from decades ago.
