Every occupation on Jobs After AI carries an AI-Proof Score from 0 to 100. This page explains where that number comes from, which research it rests on, how it was built, and what it cannot tell you.

What the score measures

The AI-Proof Score is a 0–100 estimate of how exposed an occupation's core tasks are to AI over roughly the next three to five years. Higher means safer. A score of 16 means most of the day-to-day work already sits within reach of systems in production today. A score of 94 means very little of it does.

It is an occupation-level baseline: it describes the typical task mix of a job, not any particular person doing it. The quiz starts from that baseline and moves it based on your own answers — what share of your week is routine processing, how digital your output is, whether you already use AI in the work, and how senior you are.

score = clamp( occupation_baseline + 0.65 × Σ(task / AI-use / stage modifiers), 8, 96 )

The 0.65 damping factor exists because the baseline already reflects the typical task mix of the role. Without it, the personal modifiers would count the same evidence twice.

What it does not measure

The evidence base

Baselines are built from four occupation-level source families. They measure different things and were published in different years, so they are weighted rather than averaged:

SourceWhat it measuresData vintageWeight
Microsoft Research — AI applicability scoreReal generative-AI overlap with an occupation's work activities, derived from ~100,000 anonymised Bing Copilot conversations2024 data, published 20250.40
Anthropic Economic Index — observed exposure and usageRevealed AI usage per occupation, the automation/augmentation split, and the gap between capability and actual coverage2025–20260.25
Eloundou et al. — GPT exposure (β)Theoretical share of tasks an LLM could complete with at least 50% time savingearly 20230.20
Felten et al. — AI Occupational ExposureBroad-AI (perception and prediction) exposure, pre-LLM20210.15

Two further sources act as scaffolding rather than signal: the O*NET occupational database, which supplies the task substrate all four measures are built on, and the BLS 2024–34 employment projections, used directionally to sanity-check demand. The World Economic Forum's Future of Jobs Report 2025 supplies the fastest-declining and fastest-growing lists.

Why the newer sources carry more weight

Felten (2021) and Eloundou (2023) describe pre-agent capability. Where those indices disagree with 2025–2026 usage data, the newer data decides the current horizon and the older capability ceiling informs the mid- and long-term picture.

The single most important fact behind that ordering: theoretical capability runs far ahead of actual coverage. Computer and mathematical work scores about 94% theoretically exposable on Eloundou's measure, while Anthropic observes roughly a third of it actually covered in real usage today. Capability indices set the ceiling. Usage data says where we currently are. A score built on either one alone would be wrong in a predictable direction.

How a baseline is built

  1. Anchor. Where an occupation has a direct Microsoft applicability score, or a close analog in the same occupational code, that score is the primary anchor. Where it does not, the baseline is anchored on the nearest scored occupations plus the role's membership in the Eloundou fully-exposed, Felten high-exposure, Anthropic exposed-or-zero, and WEF declining-or-growing lists.
  2. Invert to a safety scale. Higher exposure produces a lower baseline. The observed exposure scales are mapped onto the 0–100 safety axis so that the most exposed digital roles land in the teens and twenties and zero-coverage physical roles land in the eighties and nineties.
  3. Apply human-moat adjustments. Usage data systematically under-sees some occupations, because chatbots only touch digital tasks. Four moats add safety on top of the inverted exposure number (below).
  4. Apply exposure penalties. The inverse case: purely digital output, routine and repetitive tasks, transactional work with no relationship or accountability attached, and presence on the WEF fastest-declining list.
  5. Calibrate to a wide distribution. Final clamp 8–96, with the spread deliberately preserved rather than compressed toward the middle. A score that returns everyone "55, mixed" tells no one anything.

Confidence levels

Every occupation carries a confidence level alongside its score, and it changes how firmly the accompanying analysis is written:

Where the sources disagree

Six divergences were resolved by hand rather than by formula. They are listed here because a reader who knows the literature will spot them:

What this score cannot tell you

From the occupation baseline to your own score

The occupation baseline is the starting point, not the answer. Your task mix, how digital your output is, whether you already work with AI, and your seniority all move the number — in both directions. The quiz applies those modifiers and returns the score with the drivers that produced it.
