It has been noticed since the time immemorial that cognitive biases have a nasty tendency of being invisible to self (note the proverbial log in one's eye). Uncovering their own blind spot is probably the hardest task for an aspired rationalist. EY and others have devoted a number of posts to this issue (e.g. the How To Actually Change Your Mind sequence), and I am wondering if it is bearing fruit for the LW participants.
To this end, I suggest that people post what they think their current rationality blind spot they are struggling with is (not the usual sweet success stories of "overcoming bias"), and let others comment on whether they agree or not, given their impressions of the person here and possibly in real life. My guess is that most of us would miss the mark widely (it's called a blind spot for a reason). Needless to say, if you post, you should expect to get crockered. Also needless to say, if you disagree with a person pointing out your bias, odds are that you are the one who is wrong.
(Who, me, go first? Oh, I have no biases, at least none that I can see.)
Not very sure. I've heard all sorts of assertions. I'm pretty sure that sugar and other carbs are a bad idea, since I've been diagnosed as diabetic. Also that too much animal fat and salt are bad - but thinking that things are bad doesn't always stop me indulging :(
The UK government recommends five portions (handful-sized) of different fruit and vegetables per day, but I don't even manage to do that, most days.
Sadly, the last time I got an appointment to talk about my diet, the nurse I had an appointment with turned out to be fatter than I am, and absolutely everything she said has slipped my memory, perhaps because I fail to believe the dieting advice of a fat nurse.
I think if I were given a few simple "doctor's orders" about food, I might be able to follow them, but don't think I can possibly hold dozens or hundreds of rules about food in my head - which is what all the stuff I recall reading consists of.
When trying to form a dietary habit it may be useful to eat (close to) the same foods everyday for a week or two. Or add a food to eat everyday one at a time, slowly replacing bad foods with better ones.
