Sherlock Holmes knew that science and problem solving are about logic and reason, supported by facts. Creativity is the opposite of all that, right? Not so fast, according to an article and book by Maria Konnikova. Facts play a role, and Holmes had a large but carefully organized “attic” of the ones that he felt were most useful. To solve problems, you need a lot of information in your head, and access to a lot more, because you never know in advance which facts are going to combine in which way to produce an answer. The process of putting those facts together is not always cold, organized, and logical. In fact, you can’t force it. Holmes was willing to sit and contemplate as long as it took, distract his mind with music and recreational drugs, and let his mind access the facts in the background and bring him the solutions.
