>Third — I’m left wondering if a true “Deep Research” like tool would be able to provide the same analysis. I find that Deep Research is fine for secondary sources, but not for Deep Analysis of primary source data.
In the searches I have done Google's "Deep Research" has been better at providing primary data (or very convincingly fabricating).
OpenAI's version seems to more likely to give the answer that everybody thinks is true. For the blood example I could see it finding many sources that repeat the 2% claim, and accept that because everyone seems to agree, then it must be right. That's a mixed blessing in that maybe most casual users might want the commonly accepted answer, but when I have used the deep research tools, it has almost always because I know the answer everybody gives for a particular question, but I suspect it might not be based in reality. This makes my reason for wanting an automated deep research tool coinciding with the weakest area of the tool itself.
It's also been a bit eye opening how often commonly repeated but poorly founded claims, seem to turn up the same names of individuals, (or organisations, or individuals pretending to be organisations) as you trace them back.
