There's lots of common 'knowledge' in social psychology including studies done by serious reputable researchers that turns out to not be so. This is a big enough issue that it's termed the "replication crisis". So, yes, maybe. Maybe not.
My original claim is that something like that was true and what someone else was referring to and I gave you a lazy link, and you complained about the guys terrible methodology and replication. I told you that there are dozens of studies and data analyses (some are on huge data sets [1]) out there and your response is that oh no they have to be quality. That's a goalpost move from "this is bad" to "all those (that I haven't even seen) are bad."

If you've got that then show me and I'll have a look. Until then I'm going with that studies I've seen that all seem to say roughly the same thing (despite widely varying sample sizes and quality of methodology)

There are none with acceptable sizes. You're just talking.
