These 6 science-backed ways to seem more intelligent may make you seem smarter, but unfortunately the effect is only cosmetic. The sources are hyperlinked to each statement in the list.

1. Use a middle initial: it makes you seem more distinct and important
2. Look people in the eye when you talk
3. Watch what you are drinking, people holding alcoholic beverages appear less intelligent.
4. Use graphs and data visualisations
5. Wear glasses. The reason people associated glasses with intelligence is actually the same reason so many people are becoming more near-sighted.
6. Use simple language.
