"To see what is in front of one’s nose needs a constant struggle". Your bit of Orwell for the day. https://www.orwellfoundation.com/the-orwell-foundation/orwell/essays-and-other-works/in-front-of-your-nose/
@bert_hubert Deciding what is true and what is false is no small feat, it is hard. We all err, so the relevant metric is the error quantity. Future events are the ultimate test. All else can be over-fit, but the future is unknown. (even if it has its own problems like skill-luck distinction). Reflecting back, looks to me 1) a strong ego is bit of a hindrance there (even if it generally helps push through obstacles) 2) more of a narcissistic personality (rather than less) also makes it harder.
@ljupco I think Orwell's suggestion to keep a notebook is highly useful. I've also used my Twitter posts in that way. Keeps a reference of what you thought. And later you can see if you got it right. I also sometimes write blog posts for that reason.
@bert_hubert Oh - didn't know of the Orwel¬ebook story - nice! Now I'm even more glad I'd done it since ages ago. Every researcher has a "research notebook" afaik. For me that was two facing pages per one week. Nowdays that's a ~/logBook plain text file, and versioned in $HOME/.git too! :-)
