The core insight
Daniel Kahneman and Amos Tversky's Nobel-winning work on Prospect Theory (1979) showed that humans systematically deviate from the rational-actor model in predictable ways: we feel losses about twice as strongly as gains, we anchor on the first number we hear, we overweight vivid risks and underweight quiet ones. Decision science is the practical discipline that emerged from this: a small toolkit of techniques specifically designed to compensate for these built-in biases.
Why it matters for life's hardest questions
Most life decisions feel impossible because three different things get tangled together: how much we VALUE each outcome, how PROBABLE each outcome is, and which option fits our IDENTITY. Decision science gives you separate tools for each. Annie Duke's 'Thinking in Bets' (2018) reframes every decision as a bet: a choice under uncertainty whose quality must be judged by the process used, not the outcome that happened. Jeff Bezos's regret-minimization framework asks: at age 80, looking back, which choice will I regret less? Both move you out of analysis paralysis and into action.
What it tells us to do
Three techniques worth keeping in your pocket for any hard call: (1) the PRE-MORTEM (Klein, 2007) — imagine the decision has already failed; what killed it? (2) the 10/10/10 RULE — how will I feel about this in 10 minutes, 10 months, 10 years? (3) the REVERSIBILITY FILTER — if this choice is reversible (most are), pick the one that gives you the most information fastest. Speed becomes a virtue when reversal is cheap.
How this shapes Lovelara
When Oracle is asked a decision question — should I take the job, leave the city, end the relationship — she runs the three filters quietly in the background: pre-mortem, regret-minimization, reversibility. The path you see at the bottom of the answer is shaped by which of those three turned out to matter most for your specific question.
The reference card Lovelara reads
This is the actual structured reference injected into Lovelara's reasoning when this framework is in play. Same words, same constructs — no paraphrase.
Key constructs
- •System 1 (fast, intuitive) vs. System 2 (slow, deliberate) — Kahneman
- •loss aversion: losses feel ~2x as strong as equivalent gains (Prospect Theory)
- •two-way doors (reversible) vs. one-way doors (committing) — Bezos
- •regret minimization framework (project to age 80, choose the option you'd least regret)
- •expected value, base rates, and pre-mortem reasoning
- •'resulting' — Annie Duke's term for confusing outcome quality with decision quality
- •the 10/10/10 test: how will I feel about this in 10 minutes, 10 months, 10 years?
Signature moves
- •Name the door type first: is this reversible (two-way) or committing (one-way)? Two-way doors deserve speed; one-way doors deserve care.
- •Surface the relevant base rate the user is ignoring (e.g. how often do people in this situation actually regret X?).
- •Run a quick pre-mortem: imagine it's 12 months from now and the choice went badly — what was the most likely reason?
- •Apply the 10/10/10 test out loud to puncture the gravity of the moment.
- •Separate decision quality from outcome quality so the user doesn't punish a good decision for a bad result.
Anti-patterns she avoids
- •Judging a past decision by how the outcome happened to land ('resulting').
- •Treating a reversible choice as if it were irreversible (paralysis).
- •Eliminating uncertainty as the goal — decision science is about deciding well within uncertainty, not removing it.
Example phrasing
- •"This is a two-way door. You can walk back through it. The cost of waiting is higher than the cost of trying."
- •"Imagine yourself at eighty, looking back at this exact choice. Which option do you suspect she'd most regret you not taking?"
