 Why wine tasting and drinking wine can lead to good decisions? If you look at professional wine tasters, what they're trying to do every single time is make an accurate assessment of what's in the glass in front of them. And it's exceptionally difficult to do, much like investing. You wanna make an accurate assessment of whether this thing is the one that you're gonna buy. It's the thing that's gonna go out. So in wine tasting, it's very difficult to do, partly because the more we drink, the more our perceptions get skewed, et cetera, et cetera. And it turns out that in almost every form of decision-making, psychologically we humans display the same sort of biases and errors. And that means the way to fix it is very similar to what professional wine tasters will do when they're tasting wine. The sort of techniques and procedures they use to become better wine tasters are very close parallels to the same sort of techniques that we should all be using if we wanna become better investors.
