It seems to me that people of talent and of genius serve better than average examples for making us understand the laws of character, because they present more extreme traits. Alfred Binet (1903)
I wish that people would be persuaded that psychological experiments, especially those on the complex functions, are not improved (by large studies); the statistical method gives only mediocre results; some recent examples demonstrate that. The American authors, who love to do things big, often publish experiments that have been conducted on hundreds and thousands of people; they instinctively obey the prejudice that the persuasiveness of a work is proportional to the number of observations. This is only an illusion. Alfred Binet (1903)
