For example, studies finding that merely thinking about intelligent people (e.g., writing down the attributes of a professor) will actually improve performance on math tests were once widely believed, and this "intelligence priming" effect is even included in textbooks. However, recent attempts to reproduce these effects have mostly failed and this failure to replicate is true of many [http://www.nature.com/news/disputed-results-a-fresh-blow-for-social-psychology-1.12902 social priming effects] as well as other experiments in social psychology.

Many other xkcd strips have commented on the ease with which surprising and novel, but false, results can be published in the scientific literature, such as [[1478: P-Values]] and [[882: Significant]]. | Many other xkcd strips have commented on the ease with which surprising and novel, but false, results can be published in the scientific literature, such as [[1478: P-Values]] and [[882: Significant]]. | ||
