Calibration diagrams and Brier trends tell you whether your probabilities mean what they say. Habits and workflows are how you produce those numbers when you are tired, when news is loud, and when a contract you care about politically is on the screen.
Good Judgment training packaged behaviors into teachable routines; this chapter adapts those routines to wallets, journals, and Friday review blocks—not to classroom essays. Habits and workflows tell you how top forecasters produce those numbers week after week—through boredom, news floods, and the urge to trade identity instead of contract. This is the operational layer on Good Judgment methods and the journal you should already be running.
Habits do not replace probability math or platform frictions. They stop you from skipping steps when a spike tempts a chase entry.
The habit stack
Question clarity: rewrite market text in plain English before numbers—wrong resolution is uncorrectable bias. Base-rate first: outside view before scrolling feeds. Granular probabilities: thirty-seven percent, not "likely." Active open-mindedness: seek disconfirming evidence. Timed updates: scheduled revisions, not mood. Team aggregation when possible: share rationales, not just means. Post-mortems: resolve, score, change one rule.
FORECAST adapted for traders
Focus one contract and one resolution source. Outside base rate and reference class. Review inside drivers and dragonfly lenses. Estimate initial p₀ blind to market price. Compare open book; compute edge and net expected value. Adjust on news with explicit likelihoods. Size under Kelly and portfolio caps. Track journal row and calibration bin.
The gate that matters: compare happens after estimate. Reversing that trains anchoring.
Worked pass: macro binary
Contract: Fed cuts twenty-five basis points at March meeting.
Focus: FOMC statement and dots; exclude emergency-cut wording. Outside: historical cut rate given futures path maybe forty-two percent. Review: labor cooling, speeches, financial stress low. Estimate blind p₀ = forty-eight percent. Compare: market fifty-five cents, cross-venue consensus tight. Adjust: soft CPI → fifty-four percent. Economics: edge near zero after fees → no trade, shadow log. Track: bin fifty to sixty percent for later Brier.
Superforecasters pass more than amateurs. Passing is a habit, not failure.
Pass quotas
Some desks cap weekly trades; others cap daily notional. A softer fox habit is a pass quota: three intentional no-trades per week with written reason. Passes train the muscle that markets do not owe you action.
Daily and weekly rhythms
Morning: scan dossiers; no orders first thirty minutes. Midday: tier-zero and tier-one news versus open theses. Evening: scheduled p reviews only. Midweek: cross-venue drift check. Friday: mispricing audit on top three watchlist names only. Sunday: Brier bins and rule violations.
Anti-habit: refreshing price every ten minutes without a likelihood change.
Team patterns even for solo traders
Buddy pair: exchange rationales before lock. Devil's advocate: steel-man NO. Aggregation: median of independent f before size—after blind estimates, not group discussion before them (groupthink kills edge). Async shared dossier per event.
Three traders blind-submit fifty-two, fifty-eight, forty-nine percent on a state race; median fifty-two versus market fifty-seven cents suggests wait—not trade—until edge clears costs. Dissenting high inside view gets down-weighted if that trader's bins are overconfident.
Information diet tiers
Official releases and rule changes drive likelihoods. Quality polls and agency data update with care. Analyst notes supply drivers, not final p. Social sentiment is timing risk, not primary input—dragonfly assigns it a lens with low weight.
When to change your mind
Scheduled review date: full lite FORECAST. Price moved three cents without news: ignore for f. Resolution criteria changed: reset thesis. Poll inside margin of error: small Bayes nudge. Friend's tweet: no update. Thesis invalidation: exit per plan.
Changelog in journal: "p fifty-two → fifty-eight because jobs report surprised two tenths of a sigma."
Thirty-day installation
Days 1–7: clarity template on every watchlist item. Days 8–14: blind p₀ before opening apps. Days 15–21: devil's advocate paragraph. Days 22–30: Sunday bin update mandatory before Monday size-up. Keystone: one shadow forecast per day—p logged, no trade—feeds calibration without bankroll risk.
Failure modes
Empty journal means no trigger. p always equals market means laziness. Only tier-three inputs means dopamine diet. Never passing means action bias. Team discussion before votes means groupthink.
Research hygiene beyond tiers
Block thirty minutes before major releases to pre-write likelihood tables: if CPI is hot, LR band X; if cold, LR band Y. After print, fill the cell and update once. Without the table, you will anchor to the first tweet.
Keep a "drivers only" note from expert content—scenarios and definitions, not their verdict. Fox intake protects you from hedgehog charisma.
Post-mortem template
On resolution: outcome, Brier contribution, which habit broke (blind estimate skipped, red team skipped, tier-three dominance), one rule change for next month. Post-mortems are how habits compound; without them, FORECAST becomes checklist theater.
Linking habits to execution
Limit-order patience belongs in the same stack as blind p₀. No orders during the first minute of a spike unless you pre-wrote a plan. Portfolio checks before size-up stop correlated election tickets from pretending to be independent edges.
What comes next
Process without perspective on who to listen to still fails. The next chapter is Tetlock's hedgehog versus fox—why credentialed certainty often loses to agile, probabilistic forecasters on testable questions.
Key ideas to carry forward
FORECAST order matters: estimate before compare. Pass often. Shadow daily. Sunday bins. Independent median beats groupthink.
Habits feel boring until a spike arrives and the checklist stops you from buying narrative at seventy cents. Boring is the point.
Workflows are how you make fox behavior default when the hedgehog in you wants to click.
Install habits on a calendar, not on motivation—motivation spikes with news; habits survive quiet Tuesdays.
