Love a laugh? Well, it may sound strange but a leading evolutionary theorist has claimed that you can make a person laugh only in eight ways. He has also discovered that reason behind why 'jokes are funny'!
According to Alastair Clarke - who has published details of eight patterns he claims to be the basis of all the humour that has ever been imagined or expressed, regardless of civilization, culture or personal taste - he has identified the precise nature of the patterns involved, addressing the deceptively simple unit and context relationships at their foundation.
Clarke explains: "One of the most beautiful things about the theory is that, while denying all previous theories, it also unites them for the first time. For decades researchers have concentrated on limited areas of humour and have each argued for causality based on their specific interest.
"Now that we have pattern recognition theory, all previous explanations are accommodated by a single over-arching concept present in all of them.
"The eight patterns divide into two main categories. The first four are patterns of fidelity, by which we recognize the repetition of units within the same context, and the second four are patterns of magnitude, by which we recognize the same unit repeated in multiple contexts.
"What this all means is that the basic faculty of pattern recognition equips us to compare multiple units for their appropriateness within a certain context, effectively selecting the best tool for the job, and then to apply our chosen unit to as wide a range of contexts as possible, effectively discovering the largest number of jobs that tool is good for.
