Intelligence is often used as a tool to generate more sophisticated arguments for what one already believes. A higher IQ correlates with the ability to find reasons supporting your stance, not with an enhanced ability to genuinely consider opposing viewpoints.

The coming economic shift won't create a simple rich-poor divide. It will create a new four-tiered social structure based on two key traits: judgment and entrepreneurial ability. The majority who lack both will be left economically non-viable.

The stereotype of the brilliant but socially awkward tech founder is misleading. Horowitz argues that the most successful CEOs like Mark Zuckerberg, Larry Page, and Elon Musk are actually "very smart about people." Those who truly lack the ability to understand others don't reach that level of success.

Idealists often believe the best idea will naturally triumph. In reality, an idea's success is determined by the "innovation capital" of its champion—their credibility, network, and influence. The idea and the innovator's capital are a combined package, not separate entities.

Society is splitting into two groups: "post-headline" people who rely on official media for validation, and "pre-headline" people (like Elon Musk) who synthesize raw, real-time data to act before the consensus forms. This information asymmetry is becoming a primary driver of wealth and power.

The assumption that superintelligence will inevitably rule is flawed. In human society, raw IQ is not the primary determinant of power, as evidenced by PhDs often working for MBAs. This suggests an AGI wouldn't automatically dominate humanity simply by being smarter.

The U.S. military discovered that leaders with an IQ more than one standard deviation above their team are often ineffective. These leaders lose 'theory of mind,' making it difficult for them to model their team's thinking, which impairs communication and connection.

Tech leaders, while extraordinary technologists and entrepreneurs, are not relationship experts, philosophers, or ethicists. Society shouldn't expect them to arrive at the correct ethical judgments on complex issues, highlighting the need for democratic, regulatory input.

The idea of a single 'general intelligence' or IQ is misleading because key cognitive abilities exist in a trade-off. For instance, the capacity for broad exploration (finding new solutions) is in tension with the capacity for exploitation (efficiently executing known tasks), which schools and IQ tests primarily measure.
