It is not easy to get the correct answer to the above question.

Psychologists have so far not agreed on how to measure vague concepts such as creativity and intelligence. Any assertion of the relationship between these two attributes and the right-handed tendency will have to wait until we have a deeper and more accurate understanding of these concepts.

President of the United States, Barack Obama is one of the most famous left-handed people in the world.

Therefore, any scientific conclusion about the intelligence of left-handed people - a group of people who make up about 10% of the world's population - has been controversial and met many skepticism. However, a few serious studies have found interesting connections between the right hand and the cognitive skills.

Researchers found that right-handed people seem to be a bit better at learning than those who are left-handed. They also find that people who are good-handed are often weak in their study and more dyslexic. Another notable point is that up to 80% of MENSA members - organizations for people with high IQ in more than 100 countries around the world - are right-handed.
