Ask HN: Why are there so many meta studies now?

I mean foremost in topics in medicine or psychology

Lately the majority of studies that i come across appear to all be meta studies.

Which really is to sum up the results of other studies to draw conclusions?

Made even worse since a few do say they have not read the whole reports of the studies they include.

That seems like something a semi decent AI should be able to produce (?).

I would think, if you are going to draw conclusions based on other studies that spending a long time researching, communicating, and understaning each one should be required

I presume it happens because meta studies are far cheaper , far faster, and allows publishing more studies?

Cheaper means they dont need a lab, Dont need subjects, humans, or animals and can be done with less people
