Richard Wiseman, a psychologist and author of 59 Seconds: Think a Little, Change a Lot, says, ‘When you gossip about another person, listeners unconsciously associate you with the characteristics you are describing, ultimately leading to those characteristics being transferred: to you. So, say positive and pleasant things about friends and colleagues, and you are seen as a nice person. In contrast, constantly complain about their failings, and people will unconsciously apply the negative traits and incompetence to you.’
