Charlie Munger understands the unintended consequences of screening

Charlie Munger about self-improvement and solving problems:

Well the big ideas, I think you should be intelligent in improving yourself.  You’re way better to take on a really big important idea that comes up all the time than some little tiny idea that you might not face.  I always tried to grab the really big ideas in every discipline.  Because, why piddle around with the little ones and ignore the big ones.  Just all the big ideas in every discipline are just very, very, very useful.  Frequently, the problem in front of you is solvable if you reach outside the discipline you’re in and the idea is just over the fence.  But if you’re trained to stay within the fence you just won’t find it.  I’ve done that so much in my life it’s almost embarrassing.  And it makes me seem arrogant because I will frequently reach into the other fellows discipline and come up with an idea he misses.  And when I was young it caused me terrible problems.  People hated me.  And I probably shouldn’t have been as brash as I was.  And I probably wouldn’t be as brash as I am now.  I haven’t completed my self-improvement process.  But, it’s so much fun to get the right idea a little outside your own profession.  So if you’re capable of doing it, by all means learn to do it.  Even if you just want to learn it defensively.

I do not observe professional boundaries.  My doctor constantly writes, PSA test, prostate specific antigen, and I just cross it out. And he says, ‘What the hell are you doing?  Why are you doing this?’  And I say, ‘Well I don’t want to give you an opportunity to do something dumb.  If I’ve got an unfixable cancer that’s growing fast in my prostate I’d like to find out 3 months in the future, not right now.  And if I got one that’s growing slowly, I don’t want to encourage a doctor to do something dumb and intervene with it.  So I just cross it out.’  Most people are not crossing out their doctor’s prescriptions, but I think I know better. I don’t know better about the complex treatments and so forth.  But I know it’s unwise for me to have a PSA test.  So I just cross it out.  I’m always doing that kind of thing.  And I recommend it to you when you get my age.  Just go cross out that PSA test.  Now the women I can’t help.

The famous 93-year-old partner of Warren Buffet probably doesn’t need to be giving medical advice, but he’s clearly still super sharp.
