British researchers have found people with lower intelligence are more likely to be unhappy than their smarter peers.

A study of nearly 7,000 people found those in the lowest IQ range of 70-99 had the lowest levels of happiness compared with the highest IQ group (120-129), according to researchers at the University College London.

Their findings, based on data from the 2007 Adult Psychiatric Morbidity Survey in England, have been published in the journal Psychological Medicine.

The BBC reported that the researchers found low intelligence was linked to lower income and poor mental health. They have called for more help and support to be targeted at this group.

"There is some evidence that long term intensive strategies directed at young children from socially deprived backgrounds can have a positive impact not only on IQ, but also on wellbeing and life opportunities,” said Dr Angela Hassiotis, one of the authors of the report.

"Such interventions are likely to be costly, but the initial costs may be offset by future benefits such as a reduced reliance on state benefits and better mental and physical health."
