Your response to this article about how contingent advice is usually better than universal advice is to propose a universal theory?
The article talks about contingent advice being better than universal advice only in stage 3. If you're not then universal advice is helpful. I think that holds true for most people and most subjects, including myself.
Originally, I thought the article did a great job describing a common scenario that occurs usually in decision making and I wanted to describe my intuition on why I think it comes about. It's not really a universal theory, more my own digestion / explanation on the interrelation around hedgehogs vs foxes and my own interpretation of the issues that the articles describes.
I just realised my reply may have come across as mean-spirited rather than the light joke I intended. Sorry about that.
...Now that you bring it up, the OP is offering a piece of universal advice. The irony seems stronger there. Not sure if that invalidates his advice or not. Probably just invalidates taking it as a hard and fast rule.
