Human history is full of overreactions and cautious first steps toward progress. Some of today’s most ordinary items or activities sparked public outcry when first introduced. From early fears of technology to health concerns over foods, people once believed these everyday things were too risky to use. These 12 examples highlight how quickly ideas can shift from alarming to accepted.
1. Coffee

When coffee was introduced in Europe in the 1600s, some religious leaders called it the “devil’s drink.” They feared it would provoke rebellion or immorality by stimulating the mind. Others claimed it caused infertility or insanity. Eventually, it became a beloved global beverage and a cornerstone of daily routines.
2. Bicycles

Victorian-era doctors warned that riding bicycles could cause a range of health problems, including “bicycle face,” a supposed condition of permanent facial strain. Some even believed it could damage women’s reproductive organs. Despite the fear, bicycles became a major tool for independence and mobility. Today, they are associated with fitness and sustainability.
3. Books

Reading was considered dangerous at various points in history, especially for women and the working class. Critics feared books could incite rebellion, spread immoral ideas, or overwhelm fragile minds. In the 18th and 19th centuries, novels in particular were accused of corrupting youth. Literacy is now viewed as a vital skill, and reading is widely encouraged.
4. Tomatoes

In the 1700s, many Europeans thought tomatoes were poisonous due to their resemblance to deadly nightshade. Some aristocrats even got sick after eating them off pewter plates, not realizing the acidic juice was drawing out lead. This created a fear that lasted for decades. Today, tomatoes are a kitchen staple around the world.
5. Electricity

When electricity first entered homes, people were terrified it would explode, cause fires, or electrocute them in their sleep. Some refused to sleep in rooms with lightbulbs for fear of invisible dangers. Misinformation and unfamiliarity made it seem more harmful than helpful. Now it powers nearly every aspect of modern life.
6. Umbrellas

In the 18th century, umbrellas were mocked and even feared in some places. In England, coach drivers worried umbrellas would cut into their business by allowing people to walk instead of ride. Some people believed they attracted lightning during storms. Eventually, practicality won out, and umbrellas became an everyday accessory.
7. Forks

When forks were introduced to Europe in the Middle Ages, they were seen as unnecessary and even sinful. Church leaders claimed that using such tools was an insult to God’s gift of hands. For centuries, people resisted switching from knives and fingers to forks at the table. Today, forks are standard eating utensils across most cultures.
8. Elevators

Early elevators without safety brakes were considered death traps, and many people refused to use them. Even after safety features were added, fears lingered about being trapped or falling. Some buildings offered separate stairs for those too nervous to ride. Now, elevators are trusted components of everyday vertical travel.
9. Mirrors

In ancient times, mirrors were believed to capture souls or act as portals to the spirit world. Many cultures considered them powerful and potentially dangerous. Breaking a mirror was thought to bring years of bad luck. Over time, they became common objects of self-reflection and interior design.
10. Train Travel

In the 19th century, doctors warned that traveling faster than 30 miles per hour could damage internal organs or cause mental breakdowns. Critics claimed the human body was not built to handle such speed. Some passengers experienced motion sickness and blamed the train itself. Trains now represent one of the safest and most efficient forms of transportation.
11. Radio

When radio broadcasts first began, some listeners feared they were hearing ghosts or government surveillance. There were conspiracy theories about radiation and mind control through the airwaves. Public skepticism faded as entertainment and news became widespread and trusted. Radios eventually became household staples and cultural cornerstones.
12. Public Swimming Pools

Public pools were once considered breeding grounds for disease and immorality. Health officials and social conservatives warned of unsanitary conditions and inappropriate behavior. Despite early resistance, regulations improved safety and cleanliness. Swimming is now recognized as a healthy recreational activity for all ages.
