Dual System Thinking Guide

Slow Down System 1

Your excitement is System 1 — fast, associative, and driven by the reward of validation. The term sheet feels great because it signals social proof and progress, not necessarily because the terms are good. Before signing, force yourself into System 2: deliberate, effortful, and evidence-based.

Run a Pre-Mortem

Ask: "If I sign this and regret it in 18 months, what went wrong?" Write down three concrete scenarios — e.g., liquidation preference traps, board control, or a low cap on future rounds. This counterfactual thinking breaks the emotional pull.

Use an External Checklist

Build a decision matrix with objective criteria: valuation, dilution, board seats, veto rights, and pro-rata clauses. Score the term sheet against your pre-defined minimums — not against the VC's pitch. If you cannot articulate why each term is acceptable in one sentence, you are not ready.

Sleep on It, Twice

Kahneman found that System 1 anchors on the first impression. A 48-hour cooling period lets your emotional arousal decay. Re-read the term sheet after two nights, and if your gut still says yes, then and only then trust it — because now it is informed, not impulsive.

Your instinct to question the speed of your triage call is exactly the kind of reflective pause that separates good judgment from luck. In Kahneman's terms, you operated in System 1—fast, pattern-based, and often accurate, but vulnerable to bias when conditions deviate from your usual routine. The key is to identify when System 1 is trustworthy and when it isn't.

Pause and engage System 2—slow, deliberate reasoning—under three conditions: (1) when the stakes are high and irreversible, such as a possible STEMI or stroke; (2) when you notice an emotional spike, like pressure from family or a crowded waiting room; and (3) when the situation doesn't match a familiar template, meaning your "gut" is actually guessing.

A practical rule: if the decision involves life-threatening risk, ambiguity, or a novel presentation, force a 30-second checklist. Ask yourself: What am I assuming? What could I be missing? That brief cognitive override turns a habit into a hypothesis, which you can then test against objective vitals and history. You're not abandoning intuition—you're auditing it. That's the difference between a reflex and a professional judgment.

You are describing the classic tension between System 1 and System 2. Your fast grading is System 1—pattern recognition, gut feel, efficient but prone to anchoring, halo effects, and fatigue bias. The deliberate check is System 2—slow, effortful, corrective. The goal is not to eliminate intuition but to sequence it.

Design a two-pass routine. First pass: read the essay and assign a tentative holistic score using your intuitive sense. Write it down immediately. Do not adjust it yet. This captures your authentic first impression before System 2 contaminates it. Second pass: after a short break, apply a fixed rubric checklist—thesis clarity, evidence quality, structure, mechanics. Score each criterion independently. Then compare the two scores. If they diverge by more than one grade level, that is your signal to reread with deliberate attention.

To reduce bias, randomize essay order and avoid grading similar topics back-to-back. Grade all essays on one criterion at a time during the second pass, not essay-by-essay. This prevents halo effects. Finally, calibrate weekly: re-grade three old essays blind and compare to your original scores. This routine preserves efficiency—most essays need only one quick check—while catching the cases where intuition misleads.
