Minds we make and minds made up for us
An interesting thought just now. I was reading an online forum trying to divine some information or other about some topic or other. Wading through all the opinions - informed, uninformed, measured, melodramatic and in-between - I stopped to ask myself: do I really need to read all this? I'm a pretty bright guy & I have a pretty good run of trusting my own judgement. I don't really need to hear & read other people's opinions on things to have an effective and reasonable opinion of things myself.
But then the thought occurred to me in a flash: maybe all the opinions I read is the reason why I have an effective and reasonable opinion of things.
In this case correlation may be causation.
