I know I’m being silly, but my brain likes numbers like 5 and 10. I can’t imagine saying 10 to 13. And a 5 degree swing in C feels too big.
Yeah, but that’s because that’s what you’re used to with the F scale.
If you were estimating a number of tablespoons of sugar, you wouldn’t be estimating in groups of 5, because that’s crazy. You’re probably more accustomed to estimating one tablespoon at a time. The same with estimating measuring cups of milk.
Or, if you don’t cook very much, for estimating walking distances, you’re not estimating in groups of 5 miles. You might group by quarter miles and say, “It’s a quarter mile away,” or a half or something.
There’s nothing special about this scale. All of the supposed benefits are the result of your familiarity with it. Had we been using °C the whole time instead, you would be estimating degrees two at a time instead of 5, and everything would be completely normal.











99% of account managers and financial advisors are just some dude. The only sensible thing to invest in is an index fund like VOO, SPLG, FXAIX, IVV, or for non-US stuff, VEU, VSS, or something else based on an index appropriate to your needs.
Genuinely, the best known growth strategy in a capitalist market is also the lowest-brain strategy. Buy an index fund, and then do nothing.
Everything else is just giving money to someone else to do a worse job on average.
