We often mask our true preferences in public, but our data tells a different story. Explore how big data reveals the raw reality of human attraction.

In the world of big data, you don't just provide information; you provide the truth of who you are when you think no one is watching.
An audio lesson about the book Dataclysm, covering its key ideas and takeaways.






The data suggests that having a "quirk" or a unique look that some people find unattractive actually increases the amount of attention you receive. This is because of the psychology of competition; when a person is conventionally perfect, many users hesitate to message them, assuming the competition is too high. However, when someone has a polarizing appearance, those who are attracted to that specific style feel they have a "competitive advantage" and are more likely to reach out, while those who aren't interested simply stay away and leave the field clear for genuine matches.
Surprisingly, research shows that physical attractiveness has almost zero impact on whether two people actually enjoy each other's company in person. Data from "blind" dating experiments revealed that post-date satisfaction ratings were independent of a person's conventional looks. While we use attractiveness as a primary filter to select people online, it does not serve as a reliable predictor of compatibility or happiness once a real-world conversation begins.
Algorithms can predict sensitive personal traits with high accuracy—such as sexual orientation at 88% and political affiliation at 85%—simply by analyzing a user's Facebook "likes." This is possible because human behavior often follows clean mathematical patterns that machines are adept at spotting. These digital traces, along with purchase histories and social network overlaps, allow companies to map out a person's life milestones, such as pregnancies or impending breakups, often before the individual is even fully aware of them.
The data actually suggests the opposite of the common belief that the internet is killing the English language. Because of character limits on platforms like Twitter, users often increase their "lexical density," choosing more sophisticated, content-carrying nouns and verbs to maximize the impact of their message. Rather than relying solely on "netspeak," people are writing more today than at any other point in history and often use more precise vocabulary to communicate effectively within digital constraints.
Social desirability bias occurs in traditional surveys when people provide "polite" or idealized versions of their preferences to look good to researchers. Big data bypasses this "honesty gap" because digital actions—like search queries and clicking behavior—capture what people actually do when they think no one is watching. This "digital truth serum" reveals the raw reality of human nature, often uncovering biases and preferences that individuals would never admit to in a face-to-face interview.
