What is the most unprofitable thing for women to do in today's society?

If you often hang out on forums, you will see countless posts titled "XX things women should never do", but those comments have no scientific basis. Let's take a look at the latest research from countries around the world and let the data tell you what is the least cost-effective thing for women to do.

Being a strong woman is not worth it: you have to work hard all your life to earn a little more money

Researchers at the University of Essex say women who are assertive in the workplace earn an average of 4 per cent more than their more obedient counterparts, which translates to an extra £40,000 over their lifetime. However, women who were overly aggressive or had excessive mood swings earned 3 percent less than the average woman. According to the survey, women’s salary is not only related to their ability, but also closely related to their personality. A woman with a calm personality who does not fight when encountering problems will only earn 40,000 pounds less in the end than those strong women who have worked hard all their lives.

Early childbearing is not cost-effective: delaying childbearing by one year will increase lifetime income by 10%

Study finds: Delaying having a child for a year boosts lifetime earnings by 10% - A brilliant study by Amalia Miller of the University of Virginia suggests that if a woman in her 20s waits an extra year before having her first child, her lifetime earnings will increase by 10%, due both to higher wages and to longer working hours.

It's not worth not saying "I love you": one sentence is worth 160,000 pounds

Britain has released a list of the truly wealthy: a single “I love you” is worth 160,000 pounds. According to an assessment by a British survey company, when you hear the words “I love you,” you earn 160,000 pounds; if you enjoy good health, it is equivalent to owning 180,000 pounds… Things that we take for granted are so valuable. British writer Steve Henry reminds people to calculate their true “wealth.” Facts have proven that "Qiong Yao-style" couples are definitely psychological billionaires.

It’s not worth it to find a short man: it’s not easy for short people to become leaders

Research finds: People who are 1.83 meters tall can earn nearly $1,000 more per year - A recent Australian study shows that if a person is 1.83 meters tall, he can earn nearly $1,000 more per year. "Tall people often take on the role of 'leader' from a young age. Due to their stature, their peers look up to them as older brothers or sisters. Tall people unconsciously take on the role of 'leader' in the office." Of course, short men have far fewer opportunities of this kind.

It's not worth not having baby photos in your wallet: they're hard to get back if you lose them

Do you often lose things? Put a baby photo in your wallet and the chances of it being returned to its owner will be greatly increased! Last year, researchers from the University of Hertfordshire in the UK randomly placed 240 wallets on the streets of Edinburgh to observe how many would be returned to their owners. Ultimately, 42% of the wallets were mailed back. Researchers found that 88% of wallets containing baby photos were returned. The researchers believe this is because baby photos are more likely to elicit honest responses from wallet pickers. Wallets containing pictures of puppies were the second most returned wallets, with a return rate of 53 percent.
