Introvert or Extrovert? Find Out With This Lemon Personality Test

Author : Daisy Simon

People enjoy taking personality tests that uncover hidden truths about themselves. So hereโ€™s the lemon personality test, a scientific experiment that uses saliva to evaluate your personality traits and whether youโ€™re an introvert or extrovert.

According to studies, Extroverts make up the majority of the population, whereas introverts make up a smaller fraction. Then there are some who are ambiverts. But how can you know which kind you are?

What Is The Lemon Experiment?

The lemon juice experiment was developed in the 1960s by psychologists Hans and Sybil Eysenck as a technique for determining whether people are introverts or extroverts.

Many individuals find the study of personality fascinating since it can help them to express themselves better. Identifying whether one is an introvert or not, may even help to improve communication skills and how our loved ones see us.

Things You Need To Conduct The Test:

To conduct this test, all you need is a string, a piece of lemon (or simply lemon juice), a cotton swab, and yourself. Easy, right?

Instructions For The Lemon Personality Test:

  • Squeeze a drop of lemon juice over your tongue and swirl it around for 10 seconds.
  • Mop up all of the saliva with the cotton balls.
  • Put the cotton wool balls on your kitchen scales to see how much they weigh after youโ€™ve wiped it all up.
  • Compare your results to those of your friends and family to determine whose weighs more.

The Results:

You must be wondering what can a lemon tell you about your personality but as per the results, introverts produce 50 percent more saliva in response to lemon juice than extroverts. Isnโ€™t that interesting?

The Science Behind This Lemon Test

The Reticular Activating System (RAS) is the system that regulates your reactions to a variety of stimuli, such as taste and social contact. The amount of saliva you make in reaction to food โ€” in this case, lemon juice โ€” is controlled by RAS.

Lemon Personality Test

Scientists think that if introverts already have a high level of activity in their RAS as a result of being constantly aroused, a little number of stimuli โ€” such as lemon juice on the tongue โ€” is all thatโ€™s required to elicit a large response.

As a result, introverts generate a lot of saliva in reaction to a small amount of lemon juice. An extrovert, on the other hand, is unlikely to have such a strong reaction.
