Podcast: Something You Should Know
Host: Mike Carruthers
Episode: What Wikipedia’s Success Reveals About Trust & Are We All Too Fearful?
Date: November 3, 2025

Episode Overview

This episode dives into two main themes: the underappreciated power of trust, as exemplified by Wikipedia’s enduring success, and the roots and realities of modern fear—why we feel so much of it and how it distorts our view of the world. Host Mike Carruthers speaks with Wikipedia founder Jimmy Wales to uncover the lessons Wikipedia teaches about trusting strangers to do good, and with journalist Ruth DeFoster, who explores the psychology and culture of fear in society.

Key Discussion Points & Insights

1. The Test-Taking Myth (03:17–06:32)

• Debunking Common Advice:
  Mike starts off the episode by challenging the widespread advice, “go with your first answer” on tests, which has been repeated for generations.
  • Research shows people who revisit and change their test answers tend to do better overall.
  • Key insight: People remember feeling worse about switching a right answer to a wrong one (the “first instinct fallacy”) and forget the times changing was beneficial.
• Actionable Tip:
  Mark uncertain answers, return later, and don’t be afraid to change your mind.

2. Wikipedia & Lessons On Trust with Jimmy Wales

Trust as Foundation (06:33–08:52)

• Wikipedia as an "Experiment in Trust":

  • Wales illustrates how Wikipedia runs on mutual trust—users trust the site’s accuracy, and Wikipedia trusts its volunteer editors by default.
  • The decline in societal trust is a real problem; fostering a culture of trust is crucial.

• Notable Quote (Jimmy Wales at 07:15):
  “We go into restaurants all the time and people are there with deadly weapons eating next to us and you know, they’re basically trustworthy.”

Transparency & Neutrality (09:25–10:30)

• Building Trust through Transparency:

  • Wikipedia flags contested articles upfront (e.g., “The neutrality of this article has been disputed”)—a practice Wales wishes traditional media would emulate.
  • Neutrality and openness are core to Wikipedia’s credibility.

• Notable Quote (Jimmy Wales at 09:42):
  “Like, how do you build trust when people inherently start off saying, oh, what this is crazy. Like anybody can edit anything. That sounds completely insane. And why would I trust that?”

How Wikipedia Moderation & Community Work (10:43–13:43)

• Openness and Positive Contributions:

  • 99% of Wikipedia is open to editing without an account; most edits are small fixes or fact additions from well-meaning people.
  • Tools notify editors when their watched pages are changed.
  • Admins—elected by the community—can warn, block, or lock pages against abuse.
  • Most vandalism comes from curiosity or disbelief rather than malice; warnings and short blocks are often effective.

• Notable Quote (Jimmy Wales at 11:02):
  “On average, people are doing it. So there's that experience. We have to say, well, actually, it does work.”

• Community & Friendships:
  Editing niches foster friendships; shared interests bring people together, even around obscure topics.

Contrasts With Social Media (13:58–15:34)

• Toxicity Elsewhere:
  Unlike social media, Wikipedia’s system discourages toxic engagement and doesn’t reward bad actors with attention or algorithmic amplification.

Trust, Neutrality, & Donations (19:39–22:31)

• Why People Cooperate:

  • Even on divisive topics, consensus for neutrality is often achieved.
  • Wales uses the example of a Catholic priest and Planned Parenthood activist collaborating on the “abortion” article—both want fair representation of differing viewpoints.

• Financial Independence:
  Wikipedia is a charity, primarily funded by small donors, not governments or billionaires, thus ensuring editorial independence.

• Scope & Scale:
  1.5–2 billion devices access Wikipedia monthly. Content exists in many languages; separate communities maintain their own content.

• Notable Quote (Jimmy Wales at 20:12):
  “You really want to get the whole story. You want neutrality. And that's another big piece of how we think about building trust.”

The Rise of AI & Wikipedia's Future (24:17–26:43)

• Impact of AI:
  Despite the growth of AI search summaries, Wikipedia’s traffic hasn’t notably declined; AI relies on Wikipedia as a source and often cites it.

  • Users still seek out Wikipedia due to its transparency and trustworthiness compared to sometimes inaccurate AI summaries.

• On Academic Use:
  Students beware: teachers also read Wikipedia, so copying won’t fly.

3. Fear: What Science, History, and Culture Teach Us – with Ruth DeFoster

What is Fear? (30:18–30:49)

• Innate vs. Learned Fear:
  Humans are born with just two innate fears: loud sounds and falling. All others are learned through experience and culture.

• Notable Quote (Ruth DeFoster at 30:53): “Humans are only born with two innate fears, fear of loud sounds and fear of falling.”

The Problem of Too Little (or Too Much) Fear (31:12–32:40)

• Case Study: Disease Without Fear:
  Patients with Urbach-Wiethe disease can't experience fear; this can put them in real danger, as fear has evolutionary value.

• Notable Moment (32:10): “Once she was held up at gunpoint, and because she can’t feel fear, she just laughed at her attacker.” — Ruth DeFoster

Socially Constructed Fear & The Media (34:13–35:26)

• Rise of Excess Fear:
  Ruth argues that overblown, sensationalized fears are poisoning politics and daily life, amplified by social media “outrage algorithms.”

• Media Diets Skew Perceptions:
  Consuming lots of violent/crime media (true crime, terrorism coverage) increases perceived danger.

• Notable Quote (35:57): “There’s a term... ‘mean world syndrome’... People who have really heavy media diets of violent or frightening media... perceive the world as being considerably more dangerous than it is.”

The Reality of Rare Risks (36:12–38:43)

• Statistical Reality:

  • International terrorism: Risk approaches zero compared to everyday dangers (e.g., lawnmowers).
  • Air travel is far safer than car travel, despite public perception.

• Halloween Candy Panic:
  The myth of poisoned Halloween candy almost never happens—fear persists despite strong evidence.

Cycles & Myths of Fear (39:07–41:12)

• Generational Fears:

  • Mass hysteria themes repeat (e.g., Salem witch trials → Satanic Panic → QAnon).
  • Vaccine fears are centuries old, now dangerous for public health due to declining immunization rates.

• Child-Focused Fears:
  Societal fears often focus on children’s safety, frequently leveraged to justify policy or social control.

Toxins, Health Myths, and Overcorrection (42:07–44:39)

• “Toxins” Scam:
  The wellness industry exploits the vague fear of “toxins”—a clinically meaningless term, hyped by unregulated supplement sellers.

• Healthy Caution, Unhealthy Obsession:
  Balancing the natural desire to protect our children with the risk of becoming overly restrictive or developing anxiety disorders.

Stranger Danger & Overprotected Kids (44:39–47:35)

• Safer Than Ever:
  Statistically, violent crime is way down, but overprotection and “stranger danger” fears keep kids indoors—a trend Ruth laments.

  • Example: In the 1970s, kids roamed neighborhoods freely; today, their “domain” is often just the backyard.

• Parenting Trends:
  Shift from “latchkey” hands-off approach to “snowplow parenting” overcorrection; both extremes have downsides.

• Notable Quote (45:23):
  “By almost any metric, we live in an unprecedented era of safety and security... But for those of us who are in the United States and who are in the Western world, we're doing really well.” — Ruth DeFoster

5. Practical Takeaways

• Trust:
  Most people are trustworthy; systems that assume good faith (like Wikipedia) can flourish with openness and transparency.
• Overcoming Fear:
  Examine your fears—are they learned from constant media exposure, myths, or real threats?
• Media Consumption:
  Diversify your information sources and resist sensationalized, negative content that can distort perspective.
• Child Safety:
  Give children more freedom—statistically, the world is safer than ever.

Summary

This episode offers a nuanced look at trust—how Wikipedia has defied skepticism through faith in human decency and transparent safeguards—and uncovers the fog of modern fear, much of it learned and reinforced by media and culture rather than grounded in reality. Carruthers’s conversations with Jimmy Wales and Ruth DeFoster are rich with stories, analogies, and scientific insights, making this a thoughtful exploration of two forces shaping our world: what (and whom) we trust, and what we fear.
