The Death of Expertise: Why Everyone Thinks They're an “Internet Doctor” Now
The internet has fueled a crisis of overconfidence. Armed with Google searches, ordinary people dismiss experts and proclaim themselves “internet doctors,” spreading misinformation and undermining real medical knowledge and public trust.
Introduction: The Age of the Amateur Welcomes You
As the COVID-19 pandemic started spreading throughout the globe in 2020, so did a virus of a different kind: misinformation.
Millions googled, YouTubed, and Facebooked about symptoms, cures, and vaccines. And overnight, everybody became an "expert."
From turmeric remedies to hydroxychloroquine to herbal "immunity boosters," the internet was filled with guidance much of it seriously erroneous.
But this was just the latest chapter in a longer story.
The truth is, we’re living in a time when expertise itself is under siege. The same tools that democratized knowledge have also blurred the line between credible information and confident nonsense.
Welcome to the world of the Internet Doctor a place where credentials are optional, intuition trumps science, and everyone believes they “did their own research.”
A Brief History of Expertise and How We Lost It
Knowledge was hierarchical before search engines and smartphones:
- You sought advice from doctors for health.
- You phoned lawyers for legal issues.
- You relied on journalists to tell us what happened.
The gatekeepers were degrees, certifications, and professional training. Then came the internet and the world changed. Information was for anyone.
In a way, this was empowering:
- Patients could learn more about their illnesses.
- Citizens could question leaders.
- Regular people could tell their stories.
But when the price of publishing dropped to nothing, so did entry barriers to disseminating bad information.
The Information Explosion: From Search Engines to Social Media
Keep these facts in mind:
- 77% of patients now find information online about their health before they visit a doctor. (Pew Research Center)
- More than 1 billion health-related queries are made on Google daily.
- YouTube is the second-largest search engine, with tens of thousands of channels that provide unverified medical opinions.
This inflosion of information left us with a paradox:
There's more knowledge than ever but it's more difficult to know what's true.
Why We Love the Illusion of Expertise
We are programmed to like simple explanations better than complicated truths.
On social media, certainty can be mistaken for competence.
If someone tells you:
"This herb will strengthen your immunity in 3 days—no side effects!"
…it sounds a lot more reassuring than an actual doctor's:
"We don't have enough evidence to know this works."
Algorithms enhance this effect:
- Emotionally charged posts go viral.
- Simplistic, absolute statements win over nuanced, qualified guidance.
Add in relatability bias (we believe those who are "like us") and you have a perfect storm:
- Non-qualified influencers doling out health, financial, and legal tips.
- So-called experts accumulating followers merely because they're good at persuading.
The Dunning-Kruger Effect: Why Ignorance Feels Like Expertise
Psychologists David Dunning and Justin Kruger found that those who are low in competence for an area tend to overestimate their own knowledge.
This mental bias is why:
- Individuals who read a few random articles on the web think they "know as much as doctors."
- Individuals with actual knowledge are less likely to overstate their opinions.
That is, roughly:
A small amount of knowledge is a bad thing.
When "Doing Your Own Research" Goes Wrong
The saying "I did my own research" is a battle cry of the anti-expertise contingent.
These are some of the resultant mishaps when online self-diagnosis substitutes for actual expertise:
Case 1: The Cancer "Cure"
A viral Facebook post in 2019 asserted that lemon juice and baking soda cured cancer.
Thousands shared it. Some patients with cancer abandoned chemotherapy for home remedies.
Many died later.
Case 2: The Anti-Vaccine Movement
Fabricated misconceptions associating vaccines with autism were pushed by pseudo-experts and influencers.
The consequence? An epidemic outbreak of measles globally.
Case 3: YouTube Finance Experts
During the time of the crypto bubble, scores of unauthorized channels guaranteed "sure-fire profits."
Tens of millions of retail investors lost their life savings in ponzi schemes.
The Google Doctor in Your Pocket
It's not only health.
From legal consultations to do-it-yourself repairs at home to financial planning, the web has given rise to a generation of do-it-yourself experts.
Whereas some DIY education is liberating, it also poses significant dangers:
- Misdiagnosis: Diagnosing a headache as a brain tumor (or the reverse).
- Overconfidence: Assuming a few articles can substitute for years of education.
- Confirmation Bias: Selectively choosing evidence that confirms your assumptions.
Why Expertise Matters Nonetheless
Despite what everyone thinks, expertise isn't merely possessing knowledge—it's understanding how to analyze it.
For instance:
- A doctor knows how research is structured and what its limitations are.
- An accountant knows how risk assessments and market cycles function.
- A researcher can tell the difference between causation and correlation.
No amount of googling can substitute for the benefits of formal learning, experience, and peer review.
The Data: Decline of Expertise Trust
Per the Edelman Trust Barometer:
- "The last decade has seen a decline in trust among scientists, journalists, and physicians around the world.".
- Meanwhile, confidence in "people like me" has grown.
This dynamic makes it possible for influencers and conspiracy theorists to flourish.
Algorithms and Attention: What's behind it?
Why does bad advice travel faster than good advice?
Social Media Algorithms:
- Reward posts that create a high degree of emotional response.
- Encourage engagement over truth.
Google Search:
- Frequently brings up content optimized for keywords, not expertise.
YouTube:
- Suggests videos similar to what you're already watching—encouraging echo chambers.
The COVID-19 Tipping Point
The crisis created these issues impossible to dismiss:
- In India, WhatsApp forwards shared false remedies faster than public health officials could shoot them down.
- In the US, celebrity figures endorsed untested remedies.
- Worldwide, skepticism of experts spread vaccine doubt.
This wasn't a mistake it was the inevitable outcome of the death of expertise.
Why People Reject Experts
So why do so many reject professionals in favor of amateurs?
Cultural Factors:
- Centuries of abuse of power have made individuals cynical.
- Experts are elitist or tone-deaf.
Cognitive Bias:
- We like simple solutions to complicated problems.
Media Fragmentation:
- No single authority is in charge of the narrative any longer.
Commercial Incentives:
- Platforms make money from sensational reporting.
The Dangers of Fake Expertise
The price of this cultural realignment is staggering:
- Public Health Emergencies
- Delayed treatment
- Rise of disease
- Vaccine-preventable deaths
- Financial Devastation
- Individuals investing in scams due to influencer hype
- Legal Issues
- Depending on unqualified YouTubers for immigration or tax tips
- Social Polarization
- Misinformation fueling wedge issues

- Are they trained in the discipline they're writing about?
- Use Verified Platforms
- Seek out the blue check or trusted institutional sites.
- Practice Healthy Skepticism
- Beware of anyone claiming "guaranteed" results.
- Acquire Basic Research Literacy
- Recognize what evidence appears like.

Conclusion: Expertise Isn't Dead—But It's Under Siege
The web has provided everybody with a voice. That's great.
But it's also created a world in which opinion can pretend to be fact, and complacency can be mistaken for expertise. The demise of expertise is not foreordained.
But it needs to be preserved by all of us to:
- Challenging our own prejudices.
- Appreciate true training and proof.
- Accept that occasionally, the simplest solution is incorrect.
In a noisome world, expertise is more vital than ever.
