Charisma is often treated as a sign of authority, but its persuasive power can also make people more vulnerable to misinformation and manipulation. The ability to speak confidently, maintain eye contact, tell compelling stories and express moral certainty can be learned, allowing online personalities to build influence regardless of their knowledge or intentions.

The warning signs are particularly important when people discuss complex subjects outside their expertise. Confident claims about mental health, healthcare, finance, geopolitics or other major issues can sound convincing even when they distort the facts. Disagreements amplified by separate online feeds and influencers have contributed to increasingly polarised views on topics including vaccines, climate change, gender and the shape of the Earth.

Charisma itself is not new. Dictators, cult leaders and con artists have long used charm to win trust and advance their interests. What has changed is the scale of modern communication. Social media and podcasts can expose millions of people to carefully selected fragments of someone’s personality, while concealing the weaknesses and flaws that would be more apparent through sustained, personal contact.

In small hunter-gatherer communities, people had the opportunity to observe potential leaders continuously, including how they behaved under pressure. Charisma was more likely to be tested against competence, judgment and character. Digital platforms, by contrast, allow individuals to present only their most appealing qualities. Human psychology did not evolve to assess these isolated, highly edited slices of behaviour, leaving audiences susceptible to impressions that may not reflect reality.

The article argues that this vulnerability affects adults as well as teenagers. Algorithmic social media has existed for only around 15 years, and users remain largely unaware of how often its design can bypass careful judgment. The example of parenting vlogger Ruby Franke, who was jailed for child abuse after two of her children were found beaten and malnourished, illustrates the gap that can exist between an appealing public persona and private conduct.

Critical thinking is presented as the strongest defence. People should learn to assess sources, interpret information, identify bias and distinguish confidence from evidence. Considering counterarguments when an idea feels emotionally compelling, and being willing to change one’s mind, are also important habits.

Understanding the mechanics of confident communication may help as well. Learning how delivery, storytelling and body language influence an audience can make it easier to recognise when those techniques are being used to persuade or deceive.

The recommended response to a highly charismatic person is therefore not automatic distrust, but greater scrutiny. Audiences should ask what experience the speaker has, whether they have a record of dishonesty, what they might gain from a particular claim and which personal needs the message may be addressing. Charisma can attract attention, but the facts and the speaker’s conduct should determine whether that trust is deserved.
