This is why we have sample size justifications. Some people might mindlessly dismiss small N studies. But a well justified sample size (see online.ucpress.edu/collabra/art...) defends against such mindlessless.

The more simplistic the take you see on here, the more it generalizes, the more it is an act of politics, not science.
If the take comes from a scientist, they know they have no evidence for their take, or they would use it.
