It takes just 3 minutes for women to decide whether she likes a man or not, a recent study has revealed.
The research showed that the average female spends the time sizing up looks, physique and dress-sense as well as taking in scent, accent and eloquence of a potential suitor.
Women also quickly judge 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 he is Mr Right, or Mr Wrong.
The study also found women rarely change their mind about a man after their initial reaction - and believe they are 'always right' in their assumptions and judgments.
The report 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. 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," the Daily Mail quoted Kay as saying.
"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.
