In a snappy paper called ‘Consequences of Erudite Vernacular Utilized Irrespective of Necessity: Problems with Using Long Words Needlessly’ by Daniel Oppenheimer, he discovered that big words slipped into reports to make the writer sound more intelligent just doesn’t work. In a series of 5 studies, Oppenheimer created samples of vocabulary used in various passages including cv’s and essays, and then asked people to rate the intelligence of the person who wrote them. The simpler language resulted in much higher ratings of intelligence.. In other words using complex language isn’t smart.

Oppenheimer also found that writing in a hard to read font lowered peoples evaluation of your intelligence.

So simplify and use nice fonts !
