Men are more emotional than women, despite their protestations to the contrary, a “scientific experiment” on British parents has found.

Men experience greater levels of emotion than women with heart-warming material, according to the study for Royal Mail, which has used the findings to produce the “definitive” list of phrases for a successful Father’s Day card.

A group of 15 fathers and 15 mothers were presented with images and videos categorised into blissful, funny, exciting and heart-warming, such as a soldier returning from service and reuniting with his daughter, while their physiological reactions were measured using skin conductance electrodes.

Men demonstrated a marginally higher emotional reaction to the blissful, funny and exciting content compared to the women, but responded twice as strongly to heart-warming content.

An accompanying questionnaire found that even though the men reported feeling less emotion, their physiological changes showed they felt emotion more strongly.

Underneath a stereotype of a tough exterior, men are really emotional but don’t like to admit it

Mindlab founder and chairman David Lewis said: “Gender stereotypes about men being stoic and women being emotional are reinforced by our day-to-day consumption of media and our social interactions.

“We oversimplify and exaggerate perceived differences between men and women and are more likely to focus on evidence that supports existing gender stereotypes.

“This study suggests that men feel emotion just as much as women, sometimes more strongly, but are less willing to express these emotions openly due to expect-ations put on them by society.”

Royal Mail’s list of phrases for Father’s Day cards “that will tug at fathers’ heart strings” are ‘number-one dad’, ‘you’re my favourite person in the whole world’, ‘I love you’, ‘you’re the best’, and ‘thanks for everything you’ve done for me’.

A survey of 2,000 men to support the experiment found that 67 per cent thought they were more emotional than they appeared.

Some 40 per cent of 18- to 24-year-old men said they had cried in the last week and 64 per cent of all those questioned said they were surprised at how much emotion they felt when their child was born.

Stephen Agar from Royal Mail said: “Research has shown that underneath a stereotype of tough exterior, men are really emotional but don’t like to admit it.

“We’ve created an ultimate list of phrases that have been scientifically proven to move dads and really pull at their heart strings.

“We hope this helps our customers when writing and sending their Father’s Day cards.”
