A useful breakdown of why traders lose money — framed as human biology, not weak discipline, with a fix built around removing yourself from the trigger.

• Your brain runs on survival wiring built for the savanna, so panic-selling at the bottom is instinct, not a character flaw.
• Four hardwired bugs drive losses: a loss hurts twice as much as a gain feels good, people sell winners and cling to losers, trading more usually earns less, and everyone buys high and sells low.
• Studies back it up — active traders in one big sample made far less than people who just held the S&P 500, and Peter Lynch's fund returned 29% a year while the average investor in it made only 7% by jumping in and out.
• Knowing the biases does not fix them, because under real financial stress the logical part of the brain shuts off and instinct takes over.
• The proposed fix: decide entry, exit, and risk in advance while calm, then hand execution to a rules-based system or AI agent so emotion never touches the trade.

Outlook: No market call here — the takeaway is to build a tested strategy and automate execution so your wiring can't sabotage you.
