It seems that cognitive biases are as dangerous as emotional biases.
%%
SOME are, I checked 7 examples in a business context; especially the tendency to overestimate ones abilities + the bandwagon effect-error......
BUT some of TA is based on a bandwagon of sorts; good volume LOL;
but plenty of trends do well on average volume, so I will watch out for bandwagon danger.


And another example is simply psychobabel, but with a grain of truth; they called it a'' gambler's fallacy, ''that past performance could impact the future'' LOL [Thier example beating S+P500] Big problem there/ is S&P500 is not a gamble , part of the future is unknown , but SPY is not a gamble. And they used wrong logic, thier conclusion was so few managers beat SPY benchmark its a gamble LOL no its not. But sure is convenient if blames ones errors on LUCK=LOL
OF course if one does it like a gambler throwing darts
@spy prices, that could be worse than a gamble,[due to slippage bid\ ask] + not all gamblers are that stupid LOL


.
IF someone gave me a profit for it, I could dwell on ''red regret box'' ;
but until then, no problem there
