"It is more especially with respect to those unconscious elements which constitute the genius of a race that all individuals belonging to it resemble each other, while it is principally in respect to the conscious elements of their character - the fruits of education, and yet more of exceptional hereditary conditions - that they differ from each other.Men the most unlike in the matter of their intelligence possess instincts, passions, and feelings that are very similar." Gustav LeBon 1895

"Is there, then, any area outside of such already recognised influences as business management, variations in interest rates and changes in such legislative fields as taxation, to which investors will be paying increasing heed? I believe there is. For lack of a better term I will call it the psychological factors affecting security prices." Phil Fisher 1960

"Psychology plays a major role in markets, and because it's highly variable, cause-and-effect relationships aren't reliable.An investment approach may work for a while but eventually the actions it calls for will change the environment, meaning a new approach is needed." Howard Marks

"The most useful and practical part of psychology—which I personally think can be taught to any intelligent person in a week—is ungodly important. And nobody taught it to me by the way. I had to learn it later in life, one piece at a time. And it was fairly laborious. It's so elementary though that, when it was all over, I felt like a fool.And yeah, I'd been educated at Cal Tech and the Harvard Law School and so forth. So very eminent places miseducated people like you and me.The elementary part of psychology—the psychology of misjudgment, as I call it—is a terribly important thing to learn. There are about 20 little principles. And they interact, so it gets slightly complicated. But the guts of it is unbelievably important.Terribly smart people make totally bonkers mistakes by failing to pay heed to it. In fact, I've done it several times during the last two or three years in a very important way." Charlie Munger

"Most people believe that markets are driven primarily by economic factors, and that psychology plays a minor role.I take the position that markets are driven by both psychological and economic factors.I owe a great debt to economists for their inability to acknowledge the degree to which psychology moves markets." Leon Levy

"Temperament is all important.I mean, if you can’t control yourself, no matter what the intellect you bring to the process, you know, you’re going to have disasters." Warren Buffett

“When push comes to shove, what you’re always going to be fighting is yourself. Panicking, overreacting, under-reacting, refusing to observe the present, living too much in the past, wanting too much to believe in the future. So, it’s all psychological traps, because the data is there, if you want to observe.” Charmath Palihapitiya

“If you want to avoid irrationality, it helps to understand the quirks in your own mental wiring and then you can take appropriate precautions.” Charlie Munger

“Successful investing is all about behaviour and psychology. You can have the best model or analysis in the world but if you panic, you lose. Said differently, everybody has a plan until they get punched in the face. The most important thing you can do to maximise the odds of success is figure out what, if any, behavioural advantages you have or can create for yourself. What rules can you live by that will prevent you from doing something stupid especially when everyone is losing their mind?” Chamath Palihapitiya

“Confucius said, ‘real knowledge is to know the extent of one’s ignorance.’” I think it’s a nice bookend to Buffett’s idea of Circle of Competence. I think investors often work on the Circle of Competence piece but spend little time on mastering themselves… If you are looking to improve your investing batting average, rigorous scrutiny of what makes you tick is a great place to start.” Jake Rosser

"A very significant part of my philosophy has to do with managing your psychology. Markets are about the psychology of others. When are they panicking? When are they greedy? But you have those same flaws or those same potential flaws, and managing your portfolio in a way that doesn't leave you where you're panicking or overexposed to greed. If you can rule those extremes out, you'll navigate the markets well." Seth Klarman
