The coffee you drink as a pick-me-up in the morning could also make you more open to persuasion, researchers say. Evidence from a new study suggests that this happens because caffeine revs up the brain, not because it generally boosts mood.

Moderate doses of caffeine can also make you more easily convinced by arguments that go against your beliefs, say Pearl Martin of the University of Queensland in Brisbane, Australia, and her colleagues.
In 2005, her team published a paper suggesting that the compound primes people to agree with statements that go against their typical views because it improves their ability to understand the reasoning behind the statements.
