Mike's Types and tipping points 

Craig's Types:

Paradox of Choice - an observation that having many options to choose from, rather  than making people happy and ensuring they get what they want, can cause  them stress and problematize decision-making.

Schrodinger's Choices (something we just made up) - in quantum mechanics, Schrödinger's cat is a thought experiment that illustrates a paradox of quantum superposition. In the thought experiment, a hypothetical cat may be considered simultaneously both alive and dead, while it is  unobserved in a closed box, as a result of its fate being linked to a  random subatomic event that may or may not occur.

All choices exist until you make a choice.
