Matt's results
How well does Matt estimate the world?
The reasoning score rewards useful facts, a sound approach, correct math, and a final estimate close to the sourced answer. Higher is better.
Headline insight
Strongest area: Everyday life and sports
Across 83 scored problems, the most reliable patterns are easier to see by subject and reasoning method than from one overall number.
See detailed breakdown
Four parts. One reasoning score.
Useful facts + Reasoning approach + Math + Final estimate
Every reasoning score adds the points earned in four areas. Higher is better in every category.
Useful facts
Quality of remembered constants and domain anchors, sometimes called pegs.
11.9 / 30Average earned points
Reasoning approach
Whether the conceptual breakdown answered the question.
23.1 / 30Average earned points
Math
Correct arithmetic, units, and conversions.
6.7 / 10Average earned points
Final estimate
Closeness of the first pass to the sourced answer.
19.6 / 30Average earned points
Maximum points: 30 + 30 + 10 + 30 = 100. The same four components appear in each subject and model comparison below.
Published editorial grades, backfilled across the archive. Some older grades need a consistency review; these averages describe this set of problems, not a validated measure of ability. All charts use a 0-100 earned-point scale.
Every scored article is included in these aggregates. 83 of 85 published pages currently have a Reasoning score.
Reasoning score by issue
Higher is better. Issue sequence is a proxy for progress, not a verified attempt date. The unnumbered coffee issue is included in all averages, but omitted here. Changing topics and difficulty can change the trend.
Problem types
Performance by reasoning pattern.
This is the most useful view for learning transfer: the same model family can appear in politics, sports, science, infrastructure, and business news.

Subjects
Performance by subject matter.
Each article has one primary subject and one model family. These editorial groupings can change; original labels remain in the export. Small groups are especially sensitive to which problems were attempted.

How strong are the pegs?
Peg points by technical area show how accurately remembered anchors supported the estimate. The reference ledger records how often a peg appears, including in sourced checks. Frequency does not establish recall accuracy. A per-peg assessment still needs the remembered value, checked value, and whether it was recalled, guessed, or supplied.
Your version
Your first estimates are tracked separately.
Your Results shows scale accuracy, subjects, problem types, and recent attempts. Optional passkey accounts can carry that history across devices.
