[The Scientist (OP)]

What one usually does, for example, placing a book on the bookshelf always- so as to not forget what they wanted. Another example would be the way we usually tidy our tables. The slightest misplacment of another item may cause confusion to one and believe or even insist the item that they usually place there, was initially there when it was not. Another example would be where people keep their belongings in their pockets. If they usually keep their items in the same pocket and have to accept a sudden change of pockets, they mostly will usually move their hands over to the initial pocket. That is some of many theories to prove that humans are creatures of habits. It is a common human behaviour. I believe that my theory is correct after many observations. If my theory is inaccurate, please let me know your opinions. Thank you very much!
