Knuckle Theory

A theory used by measuring the number of days in a month. If your index finger touches your knuckle of your hands, the month has 31 days, while if you touch the skin of your fist, it has 30 (with the exception of February).

Scott: Dude, how many days are there in August?

Dave: 31.

Scott: Isn't it 30?

Dave: Use the Knuckle Theory.

Probadance Theory

Probadance Theory: A conceptual framework that integrates principles from Bayesian epistemology and critical rationalism to create an adaptable and self-correcting hierarchy of event likelihoods. The term combines "probability" and "dance" to emphasize its dynamic and evolving nature in organizing, evaluating, and updating beliefs about the likelihood of various events.

Ever since I started applying the Probadance Theory to my decision-making, I've been able to assess situations with greater clarity and adaptability.

The Branard Theory

The probability of beating someone in a fight is equal to 0.5, ±(The difference in height between you and your opponent)*0.1, regardless of physical ability.
In layman's terms, if you are taller than someone, you can beat them in a fight. A fact known by all tall men, and a fact discredited by all short men.

Well my 5'11" friend, since I am 6'3", I could definitely kick your ass... That's The Branard Theory for ya!
