Actually becoming more intelligent takes time and effort. Time that could be spent on bluffing it instead. Here's five quick ways to come across as clever:

1 Choose your words carefully. The boffins at American Heritage Dictionaries list the five most intelligent sounding words as epitome, finagle, gregarious, panacea and perfunctory.

 2 It’s not just the words, but how you say them. Michael Ronayne, director of the College of Public Speaking, says, “A clear, well-paced voice is a sign of confidence.”

 3 Failing that, speak faster. “The faster characters speak, the more intelligent the audience feel they come across” – says psychotherapist Tom Barber.

 4 Fix your posture. The majority of social communication is body language. "If you have a tendency to slouch, people will think of you as lazy, shy or stupid," says life coach Rebekah Fensome.

 5 Look after your looks. “Attractive people tend to appear better adjusted, more popular and intelligent,” says Dr Liam Barker. “It’s what psychologists refer to as ‘The Halo Effect’.”
