This post by Manlobbi is far from OT. So do yourself a favor by listening to - and thinking about - the 25 minute video he links. The presenter uses a lot of multi-syllable language. But the basic message is simple. If you think you really understand something, dig deeper. Then you'll begin to learn what you don't know. And then you'll make better decisions.

It clearly applies to investing. And we're now getting an object lesson on how it applies to politics - which kicks-back on economics, and thus investing. I am deeply concerned that we're about to learn a damaging lesson about how the Dunning-Kruger effect is now impacting the world. And this from a guy - me - who continues to try to keep politics off the BRK board.

So, thanks Manlobbi for sharing. I hope we are listening.

I'm forwarding the link to two groups of family members. One is our daughter and son-in-law, who will soon be retiring and having to become more skilled in investing. The other is our two grand-daughters - to promote their continued learning about human nature. The earlier you think about such things, the more valuable they become.
