There was a recent thread on whether it might someday be possible to quantify pain. The consensus seemed to be it is tricky and there are many causes and much individual variation. Yet, perhaps one day.
This begs the question on quantifying happiness, anger, curiosity or any other emotion. This thread asks you to name a unit for happiness, or any other emotion or feeling of your choice. It does not matter whether it can or should be quantified.
For example, I propose that happiness should be measured in “puppies”. I think Schulz was right about that. But what units should be used to measure other emotions?
Ignorance is not really an emotion, but the correct unit is millitrumps. Except for one exceptional case, no one has ever measured more than a few dozen millitrumps.
The unit of aggression is the tant. It takes an extremist or even a terrorist to register a whole tant. Ordinary levels of aggression may be measured in mili-tants.
