Fifty years ago, many beliefs were considered normal that would now raise eyebrows or even spark outrage. Society in the 1970s functioned with different norms, shaped by limited scientific knowledge, traditional values, and slower communication. Many of those once-common ideas now seem naive, inaccurate, or outright harmful. What was widely accepted then has often been disproven or abandoned entirely. Here are ten outdated beliefs from 50 years ago that seem absurd in today’s world.
Smoking Was Considered Harmless
In the 1970s, smoking was deeply embedded in daily life. Cigarettes were advertised during prime-time television, sold in vending machines, and even handed out at events. Many believed smoking had relaxing or appetite-suppressing effects that made it beneficial. It was common to see people smoking in hospitals, planes, and offices. Public health information about smoking’s link to lung disease and cancer was either not widespread or heavily disputed. Today, smoking is one of the most regulated consumer habits, with public bans, warning labels, and global campaigns. That it was once encouraged still shocks many people.
Seat Belts Were Ignored or Removed
In many cars, seat belts were viewed as optional or even annoying. People often tucked them behind seats or disabled warning buzzers. Safety campaigns were rare, and many drivers believed holding the wheel tightly would protect them in a crash. Even parents let children stand in the backseat or sit on laps. The lack of seat belt use led to thousands of preventable deaths. Today, laws in nearly every country mandate seat belts for all passengers, and newer vehicles come with advanced restraint systems. Looking back, the resistance to seat belts now appears reckless, outdated and uninformed.
Married Women Should Stay at Home
A widespread assumption was that a woman’s career should end once she married or had children. Many job listings even specified “male applicants only.” Employers feared married women would be less committed or too distracted by family obligations. Women who worked were often paid less and denied advancement. This belief limited economic independence and reinforced a narrow view of gender roles. Today, women make up nearly half of the global workforce, and dual-income households are common. The notion that marriage ends a woman’s ambition now feels discriminatory and outdated.
All Fat Was Bad
In the 1970s, dietary advice was centered on cutting all fat from meals. Butter, eggs, and red meat were replaced with processed low-fat products. Many people switched to margarine and sugary cereals, believing fat caused heart disease. This belief ignored the difference between healthy and unhealthy fats. Years later, research showed that some fats, like those from fish and nuts, were essential for health. The widespread fear of fat led to a surge in refined carbohydrates, contributing to other health problems. Today, balanced diets focus on quality over simple fat content.
Left-Handedness Was Discouraged
Being left-handed was often viewed as incorrect or inferior. Some schools forced left-handed children to switch hands for writing. Others were told they would face disadvantages in sports or daily tasks. Left-handed students had difficulty using classroom tools, desks, and scissors, which were all made for right-handed users. Teachers sometimes labeled left-handedness as a behavioral problem. Now, handedness is recognized as a natural trait with no bearing on intelligence or ability. Most tools are now designed to accommodate both right- and left-handed people, and forcing hand-switching is seen as damaging.
Margarine Was Marketed as a Health Food
As part of the anti-fat movement, margarine gained popularity as a heart-healthy alternative to butter. It was marketed as modern, progressive, and better for cholesterol. However, early margarine products were full of trans fats, which we now know increase the risk of heart disease. People were unknowingly trading one perceived risk for a more serious one. After public backlash and regulatory changes, trans fats were removed from many products. Today, some forms of margarine are considered safe, but the idea that all margarine was once seen as superior to butter is no longer accurate.

Tanning Was a Sign of Fitness
Having a tan in the 1970s was associated with good health and social status. People believed sunlight helped the skin and improved mood. Tanning oils were used to darken skin faster, often without sunscreen. Tanning beds became popular as a way to maintain a bronze look year-round. Few people understood the risk of melanoma or photoaging. Today, medical advice emphasizes sunscreen use and avoiding excessive UV exposure. Skin cancer rates have brought attention to sun damage. The belief that tanning made someone look healthier now feels dangerously outdated.
Divorce Meant You Failed
Getting divorced in the 1970s carried significant social stigma. It was seen as a failure of character or a breakdown of moral values. Divorced people were often viewed with suspicion, and women in particular were blamed for failed marriages. Custody laws and social support systems often favored staying married, no matter the cost. Many stayed in unhappy or even abusive relationships to avoid judgment. Today, divorce is seen more as a personal decision based on compatibility and well-being. The belief that divorce was shameful is now rejected by most societies.
Boys Should Suppress Emotion
Boys were taught that showing emotion, especially sadness, was a sign of weakness. Phrases like “toughen up” and “act like a man” were used to shut down emotional expression. This belief limited emotional development and created long-term issues around anger, depression, and relationships. Boys who cried were mocked or punished. Emotional intelligence was not considered valuable in boys or men. Today, there is increasing awareness of the importance of mental health and emotional literacy for all genders. The expectation that boys must hide their feelings now feels harmful and outdated.
Corporal Punishment Was Seen as Necessary Discipline
Spanking, paddling, and other physical punishments were used routinely in homes and schools. Many adults believed that pain taught discipline and respect. Some schools even had special tools for hitting children, and parents were expected to use force if children misbehaved. Questioning this approach was rare, and children had little recourse. Over time, evidence mounted showing that physical punishment led to emotional and behavioral problems. Today, many countries have banned corporal punishment in schools, and more parents turn to communication-based discipline. The idea that hitting children was the best way to guide them has largely been discredited.

Culture, Science and Society Evolve
The beliefs that shaped life 50 years ago now serve as reminders of how culture, science, and society evolve. Ideas once viewed as normal are now seen as incorrect, harmful, or even absurd. From smoking to seat belts to gender roles, public awareness has shifted dramatically. What seemed sensible then often lacked accurate data or ignored long-term harm. Recognizing these outdated views helps us avoid repeating the same mistakes. It also shows that social progress depends on questioning assumptions and updating beliefs. As we look back, we gain better perspective on how far we’ve come and how much more we still need to learn.
