With over 6,000 people searching Google monthly on how to take up new hobbies due to COVID-19, DIYS.com decided to share their six-month study they conducted whereby they asked volunteers to sit an IQ test before and after to discover which activities improve cerebral intelligence.
According to VeryWellMind, an average IQ test score is around 100, with different countries around the world varying between 59 and 108.
- Learning a new instrument proves to be the hobby which increases IQ the most - 9.71%
- In second place, knitting improved participants’ IQ by 9.68%
- Exercising (7.37%) and reading (7.07) rank third and fourth respectively
- Gardening places seventh with an increase of 5.10%
DIYS.com surveyed 4,694 volunteers in July 2020 asking them which activities they were interested in taking up due to lockdown. Subsequently, they were asked to test their IQ on https://www.123test.com/iq-test/. The volunteers were grouped into their respective activities and the results were noted. Once the six-month period had lapsed, DIYS.com contacted the volunteers again at the beginning of January and requested them to retest their IQ. For the volunteers who responded, DIYS.com indexed their results.
Finally, IQ scores were indexed and averaged based on group activities.
