Why Your Brain Treats Sunk Cost as a Reason to Stay

In this episode of The Money Mindset Podcast, Lucas and Luna explore the sunk cost fallacy — why we stick with bad investments, unfulfilling careers, and even half-read books just because we've already put time or money in. Using the specific example of the Concorde supersonic jet — a project that governments continued funding long after it was clear it would never be profitable — they break down the psychological trap that makes it so hard to walk away. Lucas shares research from behavioral economist Richard Thaler on 'Concorde fallacy' and explains how the same mental shortcut causes everyday money mistakes: holding losing stocks, finishing terrible movies, and renovating a house you plan to sell. The conversation offers two practical mental frames — the 'outsider test' and the 'zero-based decision' — to help listeners cut their losses before they get even deeper.
