“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.”

“There are here two assumptions about 'evaluations ', which I will call assumption (1) and assumption (2). Assumption (1) is that some individual may, without logical error, base his beliefs about matters of value entirely on premises which no one else would recognise as giving any evidence at all. Assumption (2) is that, given the kind of statement which other people regard as evidence for an evaluative conclusion, he may refuse to draw the conclusion because this does not count as evidence for him.”

“Most of our notions about the world come from a set of assumptions which we take for granted, and which, for the most part, we don't examine or question. We bring these assumptions to the table with us as a given. They are so much a part of who we are that it is difficult for us to separate ourselves from them enough to be able to talk about them. We do not think these assumptions, we think from them.”

“[T]he assumption describes our actions, not our thoughts. If you had to understand something intellectually in order to do it, none of us would be able to walk.
Economics is based on the assumption that people have reasonably simple objectives and choose means to achieve them. Both assumptions are false-but useful.
Suppose someone is rational only half the time. Since there is generally one right way of doing things and many wrong ways, the rational behavior can be predicted but the irrational cannot. If we assume he is rational, we predict his behavior correctly about half of the tie - far from perfect, but a lot better then nothing. If I could do well at the racetrack I would be a very rich man.
[R]ationality is an assumption I make about other people. I know myself.
[R]ationality is an assumption I make about other people. I know myself well enough to allow for the consequences of my own irrationality. But for the vast mass of my fellow humans, about whom I know very little, rationality is the best predictive assumption available.”

“We often hear it said in this country, and the words have a familiar smack about them, that what is wanted is a period of either firm or strong government [for India]. It is very difficult to define what is meant by that, but, assuming for a moment that we are in agreement as to what it means, I would say this. That is perfectly possible, but you can only hope to succeed on that policy alone on two assumptions; I am coming to the history in a moment. Those two assumptions are, first, unanimity among the political parties at home, and, secondly, continuity of policy. It was because both these preliminary necessities were absent in the case of Ireland that the Irish question went on, as it did, for a generation, and culminated, as it did, between the alternatives of complete surrender or war. Opinions differ as to the solution that was chosen. I, as a member of the Government at the time, supported the solution of surrender. I did not like it at the time, but I did it from conviction.”

“By the time it comes to interpretation of the substantive conclusions, the assumptions on which the model has been based are easily forgotten. But it is precisely the empirical validity of these assumptions on which the usefulness of the entire exercise depends… A natural Darwinian feedback operating through selection of academic personnel contributes greatly to the perpetuation of this state of affairs.”

“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.”

George Soros (1930) Hungarian-American business magnate, investor, and philanthropist

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.
