CORE DEFINITION

Two losing games (with negative expected value), when alternated in a specific order, can produce a winning outcome (positive expected value). That is: losing + losing = winning. -

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Nonlinear returns from strategy combination. - This is counterintuitive, but common in complex systems. For example, simply "saving money" (inflation devalues, losing) and simply "aggressive investing" (high risk, losing) may both be bad strategies, but combining the two (dynamic balanced portfolio) can achieve asset growth. Don't just look at the profit and loss of a single strategy; look at the emergent effect after combining strategies.

Anchor fast decisions

Parrondo's paradox: two games that each lose can win when alternated according to certain rules. The key is to use the coupling of "capital/state" between different games, so that losing games pave the way for winning games, similar to a "ratchet" mechanism.
