Forecasting with Accountability Loops | Generated by AI

Home 2026.05

Question: You set a calendar event a year ago as a future prediction/reminder, and now you’re thinking you should build more habits like that — using calendar events to predict the future and check back on them. Is this a good system?

Answer:

Yes, and you’re independently discovering something that serious forecasters do systematically. It has a name: forecasting with accountability loops.


Why This Works

The core mechanism: prediction → time capsule → review → calibration.

Without the review step, your brain rewrites history (“I knew that would happen” = hindsight bias). The calendar event forces an honest audit.

Superforecasters (Tetlock’s research, Superforecasting) do exactly this — write predictions with explicit probabilities, date them, review them, and track their calibration score over time. The review loop is what separates people who get better at predicting from people who just have opinions.


What to Capture in Each Event

Don’t just set a reminder. Write the full prediction at creation time:

Date: 2025-05-23
Prediction: Anthropic will cut Opus pricing by >30% within 12 months
Confidence: 75%
Reasoning: DeepSeek pressure, inference cost curves, API volume incentives
Review date: 2026-05-23

When you review, record:

Since you’re already blog/GitHub-native:

# predictions.md in your blog repo
## 2025-05-23 | Confidence: 75%
**Prediction**: Anthropic cuts Opus price >30% by May 2026  
**Review**: [fill in 2026-05-23]

## 2025-05-23 | Confidence: 60%  
**Prediction**: Still using Hermes over Claude Code in 6 months
**Review**: [fill in 2025-11-23]

Calendar event = just the trigger to open predictions.md and fill in the Review field.


The Real Compounding Value

After 2-3 years of this, you’ll have:

  1. A calibration score — do you actually know what you think you know?
  2. A map of where your reasoning was systematically off
  3. Intellectual honesty that’s rare — most engineers have opinions, few have evidence about the quality of their opinions

You’re already thinking in this direction. Formalizing it even slightly — just adding confidence % and written reasoning — makes it 10x more valuable than a bare calendar reminder.
