The "Universe 25" experiment
It is a non-sequitur only if extended too far. With respect to the intersection of instinct, incentive and consequent behavior, these experiments are useful. They are not meant to predict human behavior, as human history is rich in frameworks that help us understand why things happen and why they continue to happen. These experiments are useful in improving our understanding the importance and contribution of variables and their effects on individual and social behaviors. Universe 25, Pavlov's Dog and New Haven Frogs share fundamental similarities in design and they deliver similar value.
Invert the order of operation. Isn't it food for thought that when one creates the equivalent of a mouse welfare state, social conditions among the mice begin to follow social conditions among humans to a degree? Apparently, we're not as smart as we think we are. We need to be reminded that life needs purpose.
