How to Achieve True Happiness Using Science-Based Protocols | Dr. Laurie Santos

Psychologists define happiness (subjective well-being) as a mix of affective experience (more positive than negative emotion) and cognitive judgment (how satisfied and purposeful you feel). Many high-achieving people may have pleasant daily experiences yet feel dissatisfied when they assess their life, or vice versa. Effective happiness strategies must target both levels: improving daily emotional states and aligning life with values and meaning.

Classic and newer data show that increasing income from very low levels to a reasonable, secure level (roughly the modern equivalent of ~$75k–$125k in the US, depending on context) significantly improves well-being. But beyond that range, each extra dollar yields very small gains compared to behaviors like getting more sleep, exercising, or practicing gratitude. Rich individuals often stay stressed and unhappy because they compare themselves upward and keep shifting their happiness target instead of revising the flawed belief that “more money will finally make me happy.”

Daily data and experiments (e.g., paying people to talk to strangers on trains or at coffee shops) show that time with friends, family, and even brief conversations with strangers reliably increase positive emotion and reduce loneliness—for introverts and extroverts. People systematically underestimate how good these interactions will feel (especially introverts), so they don’t seek them out. Scheduling at least one extra real-time interaction per week—by phone, video, or in person—can substantially improve mood and life satisfaction, especially if phones are out of sight.

Simply having your phone in the room drains cognitive resources; experiments show double‑digit performance drops on math and learning tasks when the phone is nearby versus in another room. In social settings, visible phones reduce smiling and spontaneous interaction (about 30% less smiling in waiting rooms). Texting and scrolling provide a “NutraSweet” version of connection—enough stimulation to feel social but not enough to nutritionally satisfy our brains’ need for in‑real‑time, face‑to‑face (or at least voice‑to‑voice) interaction. Intentionally studying and socializing without the phone in sight is a high-yield change.

We overvalue extrinsic rewards (money, accolades, status) and quick dopamine hits, and undervalue practices that actually move the happiness needle, like social connection, sleep, exercise, and expressing gratitude or delight. We also underestimate how much we’ll enjoy talking to others, helping people, or using our strengths. Recognizing these prediction errors—and deliberately testing “small experiments” (e.g., call a friend, compliment someone, give a small gift)—helps recalibrate our internal compass toward habits that truly increase well-being.
