This experiment will use personality assessments to evaluate whether certain character traits are more common in left-handed people.
- Are certain character traits more common in left-handed people?
There has been a lot of research conducted into various aspects of left-handedness, but it is still not very clear if handedness and personality are linked. This experiment will explore this question by evaluating the prevalence of specific character traits in left-handed and right-handed people.
- Test subjects (approximately 20 left-handed people and 20 right-handed people)
- Myers-Briggs personality test
- Notebook for analyzing results
- Find the Myers-Briggs personality assessment online, and give it to an equal number of left-handed and right-handed adults.
- Calculate the percentages of each of the Myers-Briggs traits (extroversion/introversion; sensing/intuition; thinking/feeling; judgment/perception) in the left-handed and right-handed groups. Do you observe differences in the percentage of certain traits among the two groups of test subjects? Are there certain Myers-Briggs traits that are more common in left-handed test subjects?
Example: Your data shows that 14/20 left-handed test subjects are introverts and 9/20 right-handed test subjects are introverts. Therefore, 70% of your sample left-handed population is introverted, compared to only 45% of your sample right-handed population. Based on this data, you might conclude that left-handed people are more likely to have an introverted personality.
