TIL about the inspection paradox, which arises whenever the probability of observing a quantity is related to the quantity being observed. For example, if you ask students about their class size, you might get an average of 40, when the real average is 30. This is because students from larger-than-average classes are, by definition, over-represented in your sample.

Extending this concept is the waiting time paradox, which is a special case of the inspection paradox. Let's say you try to catch a bus whose average frequency is every 10 minutes. If you show up randomly at the bus stop, you might therefore expect to wait an average of 5 minutes. The reality is nearer to 10 minutes because late buses cause more passengers to wait, and thus you are more likely to be in that larger group of unlucky passengers.

Interesting. Not sure if related but I remembered about Pareto principle. These statistical phenomena always amaze me.

How I missed your casts! You didn’t show up on my feed for such a long time and I assumed you’ve stopped casting, I checked now and you didn’t. Feed is acting really weird lately. This one pushed me into a trans and I looked at a wall for couple of minutes like a crazy person 😂 enjoyed every second though.
