I’ve made an interesting observation: you lists will be quite different if you try or don’t try to recall a director’s name for each movie. The reason for this is that if you wrote one director’s name against a movie at the top of the list, you will somehow lean towards all the rest movies you know by the same director, and will write them down in their respective position of the alphabet. But if you don’t think of directors, you will probably lean towards the same actors.
