How a lemon can reveal your personality

Do you think you’re an extrovert or an introvert? To answer, you might immediately ponder how much you like going to parties and talking to strangers, or perhaps you’ve already got an answer given to you by one of those online quizzes that prompt such self-reflection. The trouble with these approaches of course is that they rely on honest insight and a hefty dose of subjectivity. Maybe you quite like parties, for instance, but nowhere near as much your best friend – does that make you an extrovert or not? A completely different approach that gets round these problems involves using a lemon – more specifically, concentrated lemon juice. This is a test with a long history in personality psychology and it’s really easy to try out at home.
