Plan 17.05s

Establish a July base rate from historical Mass Shooting Tracker July figures (sq1), adjust for 2026's year-to-date pace/trend (sq2) and the July 4th holiday spike (sq3), then blend these correlated factors via weighted average into a distribution over the answer bins.

Sub-questions (3)

sq1
Will July 2026's mass shooting count fall near the historical July average (typically the highest-count month) based on prior years' July figures?
July is consistently among the highest months for mass shootings in the Mass Shooting Tracker due to summer/holiday effects; the historical July base rate is the strongest predictor.
w=0.50
sq2
Will the 2026 year-to-date monthly trend (Jan-June) be running above the recent multi-year average pace?
Recent-year trend and 2026 momentum adjust the base rate upward or downward relative to historical July figures.
w=0.30
sq3
Will the July 4th holiday weekend produce an above-average spike in mass shootings as in prior years?
Independence Day weekend reliably elevates July counts; the magnitude of this spike shifts the total within the option bins.
w=0.20

Rationale

(a) The question resolves end of July 2026, roughly a month and a half out from the latest evidence, so substantial uncertainty remains. (b) Status quo: July is consistently the highest-count month for mass shootings due to summer/July 4th effects, with a historical mean ~85.7 but a more recent 3-year mean of ~80 and a 2026 linear projection of ~81; declining overall 2026 trend (408 in 2025, down from 504 in 2024) pulls this down, placing the modal outcome in the 76-85 or >85 bins. (c) A surprising-but-plausible outcome would be a low count (≤55), which could occur if the declining trend accelerates or if the crowd-sourced tracker under-reports, but this is unlikely given seasonal spike reliability. The Monte Carlo distribution concentrates probability in 60-100, and the mid-June pace (16 incidents June 3-12 per GVA) suggests no collapse in activity. I center the distribution around a mean of ~78-80 with std ~15, giving most weight to the 66-75, 76-85, and >85 bins while leaving moderate tail probability on lower options for the declining trend and definitional/reporting uncertainty.

## Required pre-forecast walkthrough

Before giving probabilities, address these explicitly in your rationale:
  (a) The time left until the question resolves.
  (b) The status quo outcome — the option most likely if nothing changes from today.
  (c) An outcome that would be SURPRISING but plausible.

## Calibration guidance

- **Status quo anchoring.** Good forecasters put extra weight on the status quo option because the world changes slowly most of the time.
- **Leave moderate probability on most options.** Good forecasters don't drop options to ~0% — leave ≥3-5% on every option to account for unexpected outcomes, unless you have strong specific evidence ruling them out.
- Avoid uniform-distribution laziness — most options are not equally likely.
- **Anchor on prediction markets.** If liquid market prices (Polymarket / Kalshi) for these options appear in the evidence, treat them as a strong prior and stay close to them absent specific contrary evidence.
