News reports events rather than uneventful periods of peace, so persistent coverage of violence does not reveal its underlying rate. Pinker argues that historical and global comparisons show major declines in war, homicide, and crime despite a continuous supply of alarming incidents.

Headlines select events rather than absences
Violence can fill the news even while its rate declines
Large peaceful regions receive little equivalent coverage
Historical homicide rates provide a more meaningful baseline

“you can't get an accurate picture of the world by looking at the headlines.”
Steven Pinker · 10:13

“The headlines are about things that happen, they're not about things that don't happen.”

The U.S. Crime Decline Does Not Have One Clever Explanation

Pinker rejects excessive confidence in neat explanations for the large decline in American violent crime. Smarter policing, more police, and broader cultural shifts may all have contributed, but the complete causal mixture remains unknown.

Violent crime fell to nearly half its peak
Crime continued falling during the Great Recession despite contrary predictions
Single-factor theories such as lead or abortion may be inadequate
Policing and unexplained cultural changes may have acted together

“The honest answer is, no one really knows what all the causes were.”
Steven Pinker · 16:32

“it may be that a number of things went right around the same time.”

Why Tweets and Text Messages Will Not Ruin Language

People command multiple styles and adapt their language to different situations and media. Informal digital writing therefore does not automatically replace lectures, formal prose, family conversation, or ceremonial speech.

Writing is not one uniform activity
People maintain distinct styles for distinct contexts
A text message and a funeral oration serve different purposes
One medium cannot represent the trajectory of language as a whole

“we tailor our our language to the medium.”
Steven Pinker · 20:17

“Text message is going to be different from a funeral ooration.”

The Split Infinitive Rule Is a Grammatical Superstition

Pinker argues that several familiar writing prohibitions were imposed through misguided analogies rather than the natural grammar of English. The rule against splitting infinitives came from Latin, while respected English writers freely ended clauses with prepositions.

Not every classroom rule reflects English grammar
Latin structure was incorrectly imposed on English infinitives
Splitting an infinitive can be clear and natural
Canonical writers violate alleged rules without producing bad English

“There's absolutely no reason to avoid a split infinitive.”
Steven Pinker · 23:30

“The whole rule came from a kind of thick witted analogy to Latin, where you can't split an infinitive.”

Why CRISPR Is Unlikely to Produce Designer Genius Babies

Pinker distinguishes editing a disease-associated gene from engineering complex traits such as intelligence, musicality, or athleticism. Such traits appear to involve hundreds or thousands of genes with tiny individual effects and potentially dangerous trade-offs.

Complex traits do not come from one decisive gene
Many genes contribute tiny effects to intelligence and personality
A beneficial variant may also increase disease risk
Embryo editing offers uncertain gains alongside serious downside

“there ain't no i Q gene.”
Steven Pinker · 41:57

“There is a genetic basis to talent and personality, but seems to be distributed across hundreds or thousands of genes, each with a tiny effect,…”

Why Your Detailed Visual World Is Partly an Illusion

Human vision feels uniformly detailed, but sharp acuity occupies only the small region currently receiving direct gaze. Rapid eye movements, memory, and expectations let the brain construct the impression of a continuous, detailed scene.

Visual cognition interprets what the eyes detect
Acuity falls dramatically outside the point of gaze
Rapid eye movements conceal the limitations of peripheral vision
Expectations and memories help construct perceived continuity

“your brain constructs an illusion of a continuously detailed visual world.”
Steven Pinker · 06:28

“we rely on expectations and memories.”

Why Words Sometimes Sound Like Their Meanings—but Usually Do Not

Some words appear to have sounds that fit their meanings, creating a limited correlation between sound and concept. Pinker argues that this effect cannot dominate language because otherwise unfamiliar languages would be immediately intelligible.

Some speech sounds evoke qualities associated with meaning
Sound symbolism produces only a limited correlation
Most word meanings are conventional and arbitrary
The effort required to learn another language demonstrates that arbitrariness

“most of the language is arbitrary, but there is a little bit of correlation between sound and meaning.”

How Literacy May Have Accelerated Humanitarian Reform

Pinker proposes that cheaper printing, rising literacy, and public debate helped expand empathy and expose destructive beliefs during the Enlightenment. He treats this as a conjecture rather than a settled single-cause explanation and emphasizes the importance of free expression.

Printing costs fell before broad industrial prosperity arrived
Books, newspapers, pamphlets, and urban discussion connected more people
Reading other viewpoints may broaden empathy
Open criticism can filter false and toxic ideas
Educated intellectuals can still advance destructive ideologies

“It's harder to dehumanize people when you read their words, when you see what life was like from their point of view.”
Steven Pinker · 14:07

“when you have freedom of speech, freedom of expression, so you don't get thrown in jail by criticizing a bad idea, then it's more likely…”

Why an Involuntary Expression Can Make a Message Credible

Facial expression and tone can reveal whether a threat, promise, or emotion is sincere because most people cannot control these signals perfectly. Genuine smiles, for example, tend to engage the eyes as well as the mouth.

Expressions supplement spoken claims with credibility signals
Anger can make a threat appear more sincere
Involuntary signals are difficult to imitate consistently
Genuine and performed smiles often recruit different facial patterns

“threats are more credible when they're delivered with an angry expression and tone of voice, because they are involuntary”
Steven Pinker · 27:57

“the sincere smile as along with a crinkling of the eyes, not just the mouth in a U shape.”

What the Broken-Windows Effect Actually Claims

Visible disorder may communicate that local rules are not enforced, increasing the likelihood of further violations. Pinker says experiments support some effect from restoring order but cautions that it cannot receive all the credit for crime reductions.

Disrepair acts as a social signal
Graffiti and turnstile jumping can imply weak enforcement
Improving visible order may reduce crime
The effect is contributory rather than a complete explanation

“if a neighborhood shows signs of disrepair, the famous broken windows, graffiti, turnstile jumping, and so on, then that conveys the message that that this…”

“It doesn't deserve all the credit, but it may be deserved part of it.”

Why Great Powers Largely Stopped Fighting One Another

Pinker describes the Long Peace as the post-Korean War absence of direct war among great powers. He points to trade, stable borders, democracy, and declining glorification of military sacrifice as reinforcing explanations rather than one definitive cause.

Great-power warfare was historically common
Trade raises the cost of attacking customers and supply chains
International norms discourage conquest and forced border changes
Democracies are somewhat less likely to fight one another
Modern societies place greater value on individual life

“When you when there's more trade, there is less of an incentive to go to war.”
Steven Pinker · 39:45

“You don't kill your customers because your supply chain or your supply chain exactly”

Pinker’s Advice to Students Considering a Difficult Academic Career

Pinker advises genuinely passionate and capable students not to abandon intellectual work merely because the academic job market is discouraging. Turnover continues even in contracting fields, and deep motivation makes the sustained work required more achievable.

Passion must be strong enough to sustain intensive work
Contracting fields still experience retirements and turnover
Capability and dedication matter alongside enthusiasm
Law, finance, and consulting should not become automatic defaults

“if it excites you enough that it doesn't feel like work but it feels like play, there will always be openings.”
Steven Pinker · 50:20

“it really is still possible to make a career in what you what you love.”
