One nice recent study involved 218 Dutch students being asked to solve a Sudoku puzzle and complete a word search in a fixed time of twenty-four minutes. Participants in the experiment were randomly as signed to one of three treatments: one where they were forced to multitask; one where they could organize their work by freely switching between the Sudoku puzzle and the word search; and one where they performed the tasks sequentially. They were awarded points for each correctly filled Sudoku cell and each word found. The total points scored were lowest in the first group and highest in the third. 35 These results suggest that having a clear schedule of work is better for productivity So multitasking might sound cool, but it actually makes you a fool.
