Note from Mason I. Bilderberg

How many people must be in a group for the odds of two people in the group having the same birthday reaches a statistical likelihood better than 50%?

The number is so surprisingly few that some people attribute a birthday match in such a small group to something akin to a sign from the heavens. They ask, “What are the odds?”

But did you know, in a group of 50 people, there is a 97% statistical chance of two people having the same birthday? Psychics use these types of statistical illusions to give audiences the impression that such occurrences are “a sign from above!”

I’d love to be in a group of 50 people when it is discovered that two people have the same birthday and the psychic asks in a mysterious tone, “What ARE the odds?” . . . just so i can yell back “97% you freakin’ charlatan!”

Wikipedia explains all the math, as does the video below.

Correlation CAN Imply Causation! | Statistics Misconceptions

This video is about how causal models (which use causal networks) allow us to infer causation from correlation, proving the common refrain not entirely accurate: statistics CAN be used to prove causality! Including: Reichenbach’s principle, common causes, feedback, entanglement, EPR paradox, and so on.

This (does not equal) That
