Which type of personality are you? The "Lemon Test" will point to the truth

There are many tests that help determine personality, but the "lemon test" is quite unusual. In the 1960s, Hans Eysenck proved that a sour fruit could "unmask" an introvert and an extrovert.

There are many psychological tests and puzzles that help define our personality. We often treat them as a form of entertainment or a "pastime", but sometimes such fun can shed new light on ourselves.

In 1967, psychologist Hans Eysenck conducted an unusual test. The scientist checked whether the taste of a lemon could identify an extrovert and an introvert. The "sour experiment" proved to be an exciting study that yielded unexpected results.

Psychologist Hans Eysenck conducted personality studies, focusing his efforts primarily on extroverts and introverts. Using a sour taste, he wanted to see if it was possible to distinguish between these two types. If you want to perform a test with a lemon, it might be worthwhile to conduct it in a larger group, for example during a house party with friends. This way, it will be possible to compare the results with other people.

How to perform the "lemon test"? First, cut the fruit into quarters and remove the seeds from them. Then use a cosmetic cotton swab or cotton to wipe your tongue dry. When you remove the excess saliva, weigh the swab and record the result.

Then, directly press a few drops of juice from a quarter of a lemon into your mouth. Spread it around in your mouth and wait about 10 seconds. In the next step, swallow the juice and wait a few more seconds. Take a second cotton swab and collect all the saliva accumulated in your mouth. Weigh the second cotton swab and compare the result with the previous one.

Eysenck in his study noted that introverts in response to lemon juice can produce up to 50 percent more saliva than extroverts. For introverts, the swab after the "acid test" should be significantly heavier than the first one. On the other hand, for extroverts, the difference will be minimal.

The results are due to the Reticular Activating System (RAS), which is a part of the brain that deals with, among other things, information processing, or reactions to stimuli, including food and social contact. Eysenck and his wife, Sybil, shared the results of a study in a work published in 1967.

It has been proven that introverts respond more intensely even to subtle stimuli. In contrast to introverted people, extroverts require a stronger stimulus to elicit a similar response.
