   Corrected an overstated psychological generalization: the article claimed present bias 'is the primary driver of undersaving for retirement,' but behavioral economics research (Laibson's hyperbolic discounting model, Thaler and Benartzi's Save More Tomorrow research, EBRI/DOL data on plan access, and Lusardi/Mitchell's financial literacy research) shows retirement undersaving is multi-causal, with income and liquidity constraints, lack of access to employer-sponsored plans, and financial literacy gaps at least as significant as present bias.

   What the page claimed

   Article presented one real, well-documented behavioral bias as the single dominant cause of a complex, multi-causal financial phenomenon.

   What was corrected

   Reframed present bias as one of several well-documented contributors to retirement undersaving rather than the primary driver.

   Why: This finding was originally identified by Codex's fact-check pass. The article's loss-aversion definition (losses feel 'roughly twice as painful' as equivalent gains) was already appropriately hedged with qualifying language and required no correction, consistent with the real Kahneman-Tversky prospect theory literature verified elsewhere in this fact-check project.
