Many of us don't have to.
I realized at some point that I was literally forgetting what happened. I took anecdotal notes to be able to accurately describe behavioral situations, and rereading them mere hours later, I couldn't actually autibiographically recall many of these incidents.
I think it's what allowed me to have normalish evenings after insane work days. Otherwise, the stress would be completely overwhelming.

Which is why I liked Warren Buffet's approach, let the writer write after talking with people. No interference. Of course, his is a biography.
You could remember bad stuff but you are not incentized to write it down.
Then how are they both different?
Won't there be a correlation?
Or am I missing something?
Bias on how you retell your own story is, as you say, a fairly obvious concern, so (for the purposes of this discussion) written autobiographies being biased is completely uninteresting.
Rather, it's the fact that your recollection of events biases towards the positive that's the novel, interesting information.
