In the latest issue of WISU, our colleague Prof<\/a>. Dr. Florian Bartholomae<\/a> (Munich Business School) breaks down the Prisoner’s Dilemma, arguably the most famous thought experiment in economics and why it still matters far beyond the interrogation room.<\/p>\n\n\n\n

The uncomfortable truth: Even when both players act perfectly rationally, they end up locked into the worst collective outcome. Not because anyone is greedy, irrational, or „bad“, but because the incentive structure makes betrayal the smarter individual move, every single time.<\/p>\n\n\n\n
