Letters give impression of intelligence - namely middle initials

President Higgins has been wise to hold onto the middle initial ‘D’ in his name.

A new study by the University of Limerick has found that using a middle initial gives a strong impression of intellectual ability.

Researchers Dr Wijnand A P van Tilburg (University of Southampton) and Dr Eric R Igou (University of Limerick) document that people can benefit from displaying their middle initials.
