“The use of "nurture" as a synonym for "environment" is based on the assumption that what influences children's development, apart from their genes, is the way their parents bring them up. I call this the nurture assumption. Only after rearing two children of my own and coauthoring three editions of a college textbook on child development did I begin to question this assumption. Only recently did I come to the conclusion that it is wrong.”

Soros on Soros (1995)
Context: The prevailing wisdom is that markets are always right. I take the opposition position. I assume that markets are always wrong. Even if my assumption is occasionally wrong, I use it as a working hypothesis. It does not follow that one should always go against the prevailing trend. On the contrary, most of the time the trend prevails; only occasionally are the errors corrected. It is only on those occasions that one should go against the trend. This line of reasoning leads me to look for the flaw in every investment thesis.... I am ahead of the curve. I watch out for telltale signs that a trend may be exhausted. Then I disengage from the herd and look for a different investment thesis. Or, if I think the trend has been carried to excess, I may probe going against it. Most of the time we are punished if we go against the trend. Only at an inflection point are we rewarded.
