Category Flexibility

Ability · O*NET work requirement

The ability to generate or use different sets of rules for combining or grouping things in different ways.

In the O*NET occupational database, Category Flexibility is an ability that work requires. O*NET rates how important it is (1–5) and what level of it a job needs (0–7) for every U.S. occupation. It is rated as important (3 or higher) in 704 of 894 occupations.

Breadth here means how widely O*NET rates this ability as important across occupations — not that it is rare, high-paying, or currently in employer demand.

Ranked by O*NET importance to the occupation (1–5). Bars are sized against the 1–5 scale; the level column is what depth of the ability the job needs (0–7).

How AI is used by roles that need Category Flexibility

This ability is not itself "being automated" — but we can look at the roles for which O*NET rates it important and ask how those people actually use AI. This rolls the Anthropic Economic Index per-role signal up across those roles (importance-weighted). 61.5% of the 704 roles where this is important carry observed AI-usage data (433 roles).

Across those roles, 46.5% of AI conversations are people working with AI and 32.0% hand a task to AI , with an average autonomy of 3.59 / 5.

Collaboration pattern Share What it means
directive 29.5% AI does it; you give the instruction
task iteration 24.1% you and AI go back and forth
learning 19.5% you ask AI to explain or teach
validation 2.9% you do it; AI checks your work
feedback loop 2.6% AI does it, then adjusts from your feedback

Roles behind this signal

The roles where this ability is most important and that also have the most AEI data. "Works with AI" is the role's share of conversations that augment rather than automate.

Source: Anthropic Economic Index (2026-01-15-v4-plus-2025-03-27-v2) over a sample of Claude.ai Free and Pro conversations — not all AI tools and not the whole workforce. Shares are of observed conversations, weighted by how important this ability is to each role; some conversations are left unclassified by Anthropic's taxonomy, so shares need not sum to 100.

Industries that concentrate this

Where Category Flexibility matters most across the economy. Employment reach is the share of an industry's workers in occupations that significantly rely on Category Flexibility (O*NET importance ≥ 3 of 5). Concentration compares that reach to the national average industry, so a value above 1× means the requirement is more pervasive here than across the economy as a whole.

Nationally, about 59.7% of workers are in occupations that significantly rely on Category Flexibility (measured across 67 industries).

Sectors with the most such workers

Health Care and Social Assistance 15,255,960 66.0%

Reach is a measure of how widespread a requirement is across an industry's workforce, not how intensively any individual uses it. Sector worker counts come from BLS OEWS employment; the significance threshold and tool use come from O*NET. Industries shown by concentration are filtered to a real worker base so a tiny specialty cannot top the list on rounding.

Capabilities required by many of the same occupations — a measure of which skills, knowledge and abilities tend to travel together, not a judgment of similarity.
