Money Traps

Money traps are thinking bugs that show up when you earn, spend, save, invest, or gamble. They are often studied in behavioral economics: loss aversion, mental accounting, sunk costs, and the way “free” or house money change risk-taking.

These patterns matter because the cost is concrete - missed returns, overspending, clinging to losing positions, or avoiding looking at the numbers. Spotting them helps you decide on future value, real purchasing power, and risk that actually fits your plan, instead of the story your mind tells about the money.
Loss Aversion You feel losses more sharply than equivalent gains, and that asymmetry steers you away from good bets and toward bad holds. 81 · Severe LA Sunk Cost Fallacy You continue a behavior or endeavor because of previously invested resources. 73 · High SCF Mental Accounting You sort money into separate mental buckets and then spend, save, or risk each bucket by different rules. 71 · High MA Money Illusion You react to the number on the paycheck or price tag and miss what that number actually buys. 68 · High MI Relative Income Trap You feel rich or poor mainly by rank against peers - so raises and upgrades fail to satisfy once the reference group moves too. 78 · Severe RIT Disposition Effect You sell what is up and hold what is down because paper gains feel safe to bank and paper losses feel too painful to admit. 73 · High DiE Hyperbolic Discounting You prefer smaller, immediate rewards over larger, delayed ones - especially when "now" is close. 74 · High HD Denomination Effect The same total feels harder to spend as one large bill than as many small ones - so form, not only value, steers the wallet. 45 · Low DE Mere Ownership Effect You value things more simply because you own them - even when an identical item would look ordinary if it belonged to someone else. 61 · Moderate MOE Payment Decoupling Frictionless payment separates the purchase from the felt cost, so spending rises without the usual brake. 71 · High PDec Pain-of-Paying Blind Spot You fail to notice that spending should hurt more - so purchases pass without the brake you think you have. 66 · High PPB Subscription Inertia Auto-renewals keep charging because canceling takes effort - so unused services quietly become a permanent line item. 64 · Moderate SubI Zero-Price Effect The word free switches your brain into a different mode - and you overvalue the free option while ignoring what it costs you. 61 · Moderate ZPE House Money Effect After a win, profits feel like play money - so you take risks you would never take with your paycheck. 68 · High HME Naive Diversification You "diversify" by splitting evenly across whatever options are in front of you - even when those options overlap or do not match your risk needs. 59 · Moderate NaD FOMO Investing You buy because others are winning and you cannot stand missing the move - not because the asset fits your plan. 75 · Severe FOI Ostrich Effect When the numbers might hurt, you stop looking - and bills, balances, and portfolio problems grow in the dark. 72 · High Ost Gambler's Fallacy You treat independent random events as if a streak is "due" to reverse - as if chance keeps a fairness ledger. 60 · Moderate GF Hot-Hand Fallacy You believe that a person who has experienced success is more likely to continue having success. 58 · Moderate HHF
