Preview — Chapter 01: The Truth about Relativity
Most choices are not made in isolation but in comparison to something else. Relativity drives decision-making, meaning people judge value based on surrounding options rather than intrinsic worth. This explains why restaurants add expensive dishes to menus: they make the moderately priced items look like bargains. Similarly, marketers use “decoy” products to push consumers toward a desired option by skewing perceptions. The relativity trap shows up in careers, housing, and even relationships. People constantly compare themselves to peers, neighbors, or colleagues, leading to envy or misplaced priorities. Instead of asking “Is this right for me?” the mind defaults to “How does this compare?” This fuels dissatisfaction because comparisons never end - there is always someone with more, better, or newer. The key takeaway is that relativity distorts judgment. Recognizing when comparisons are influencing choices allows people to step back and evaluate based on personal needs. Freedom comes from breaking away from the endless cycle of measuring life against others and focusing instead on intrinsic value.
