Hugh Pickens writes "Discover Magazine reports that despite the average person shaking hands nearly 15,000 times in a lifetime, one in five (19 per cent) admit they hate the act of the handshake and are unsure how to do it properly, regularly making a handshake faux pas such as having sweaty palms, squeezing too hard or holding on too long while over half the population (56 per cent) say they have been on the receiving end of an unpleasant handshake experience in the past month alone. But help is at hand as scientists have developed a mathematical equation for the perfect handshake taking into account the twelve primary measures needed to convey respect and trust to the recipient. “The human handshake is one of the most crucial elements of impression formation and is used as a source of information for making a judgement about another person," says Professor Geoffrey Beattie, Head of Psychological Sciences at the University of Manchester, who devised the formula. "A handshake reveals aspects of the personality of the person giving it – for example, a soft handshake can indicate insecurity, whilst a quick-to-let-go handshake can suggest arrogance – so it is surprising that up until now there has not been a guide showing people how they should shake hands." The research was performed at the behest of Chevrolet as part of a handshake training guide for its staff and is meant to offer peace of mind and reassurance to its customers. A full guide to the perfect handshake is available on Flickr."
