It takes a woman just 3 minutes to make up her mind about Mr Right

A woman takes just three minutes to decide whether she likes a man, according to a new study.

The research showed that the average woman spends the time sizing up looks, physique, and dress sense as well as taking in the scent, accent, and eloquence of a potential suitor.

The woman also quickly judges how he interacts with her friends and whether he is successful or ambitious.

According to the study, women believe 180 seconds is long enough to gauge whether or not someone is Mr Right or Mr Wrong.

The study also found that women rarely change their mind about a man after their initial reaction — and believe they are always right in their assumptions and judgments.

The study was commissioned among 3,000 adults to mark the release of Instinct, a new book by Ben Kay.

"I think a lot of people believe in trusting their instincts when dating," the Daily Mail quoted Kay as saying. "It makes it seem more magical, like it's coming from somewhere deeper. But it's surprising how quickly women make a decision. That's barely enough time to finish a drink together.

"It's interesting that so many women trust their instincts and yet still give men the opportunity to change their minds. Some men might think this is leading them on, but I would imagine most women just want to give every bloke a fair shot," Kay added.
