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.

You continue a behavior or endeavor because of previously invested resources.

SCF
Mental Accounting

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.
