What kind of figure this source publishes
The BLS category is a relative rank, not an absolute level, and it is not a first-hand measurement: it groups an occupation's percentile ranks across several published studies into four bands. It is not an employment or wage forecast, not a probability of adoption, and it does not separate automation from augmentation.

Values in this tab are predicted labels, not observations. Eloundou et al.

The unit and the meaning differ from the observed shares (%) in the other tabs, so do not place them on the same axis.

0.37/ 3· Robot exposure index
Scale, basis and source
Each physical task is graded 0–3 by the setting in which robots that have been deployed, sold or demonstrated could do it (0 none · 1 purpose-built robot settings such as a fenced machine cell or a bottling line · 2 structured facilities such as a hospital pharmacy or a container port · 3 unstructured settings such as a private home or a construction site), and the grades are averaged by share of working time
Physical tasks among this occupation's O*NET 29.3 tasks
Anthropic estimated the grades and time shares with Claude Opus 5 using web search, as of 2026.
The robot exposure index is a different measure from the AI exposure figures on this site and cannot be added to or compared with them. It does not measure actual adoption or cost, and 0 also covers occupations with no physical tasks.

ILO occupational description
AI Changing Work links the ISCO-08 unit groups below to this occupation by applying the U.S. Bureau of Labor Statistics crosswalks (2018 SOC to 2010 SOC, 2010 SOC to ISCO-08) as published, without case-by-case selection; each link may be whole or partial.
- ISCO-08 2131Biologists, Botanists, Zoologists and Related Professionals
The definition, tasks and examples below are the ILO's description of that unit group, not of this occupation.
Biologists, botanists, zoologists and related professionals study living organisms and their interactions with each other and with the environment, and apply this knowledge to solve human health and environmental problems. They work in diverse fields such as botany, zoology, ecology, marine biology, genetics, immunology, pharmacology, toxicology, physiology, bacteriology and virology.
Tasks
- (a) undertaking research in laboratories and in the field to increase scientific knowledge of living organisms; to discover new information; to test hypotheses; to solve problems in areas such as the environment, agriculture and health; and to develop new products, processes and techniques for pharmaceutical, agricultural and environmental use;
- (b) designing and conducting experiments and tests;
- (c) gathering human, animal, insect and plant specimens and data, and studying their origin, development, chemical and physical form, structure, composition, and life and reproductive processes;
- (d) examining living organisms using a variety of specialised equipment, instruments, technologies and techniques such as electron microscopes, telemetry, global positioning systems, biotechnology, satellite imaging, genetic engineering, digital imaging analysis, polymerase chain reaction and computer modelling;
- (e) identifying, classifying, recording and monitoring living organisms and maintaining databases;
- (f) writing scientific papers and reports detailing research and any new findings which are then made available to the scientific community in scientific journals or at conferences for scrutiny and further debate;
- (g) designing and carrying out environmental impact assessments to identify changes caused by natural or human factors;
- (h) providing advice to governments, organizations and businesses in areas such as conservation, management of natural resources, the effects of climate change and pollution.

ESCO occupational vocabulary
Each entry below is matched to this occupation in the published ESCO-O*NET Crosswalk (version 1, 2022). The match types are that crosswalk's; the wording is AI Changing Work's.
- biologistESCO 2131.4This occupation is narrower
Biologists study living organisms and life in its broader extent in combination with its environment. Through research, they strive to explain the functional mechanisms, interactions, and evolution of organisms.
- biochemistESCO 2131.4.2Overlapping, not the same
Biochemists study and perform research on the reactions caused by chemicals in living organisms. This includes performing research for the development or improvement of chemical-based products (e.g. medicine) aimed at improving the health of living organisms and at better understanding their reactions.
- bioinformatics scientistESCO 2131.3Overlapping, not the same
Bioinformatics scientists analyse biological processes using computer programmes. They maintain or construct databases containing biological information. Bioinformatics scientists gather and analyse biological data and may also assist scientists in various fields, including in biotechnology and pharmaceutics. They perform scientific research and statistical analyses, and report on their findings. Bioinformatics scientists may also collect DNA samples, discover data patterns and conduct genetic research.
- biophysicistESCO 2131.4.4Overlapping, not the same
Biophysicists study the existing relation between living organisms and physics. They conduct research on living organisms based on the methods of physics that aim to explain the complexity of life, predict patterns, and draw conclusions about aspects of life. Biophysicists' research fields cover DNA, proteins, molecules, cells, and environments.
- microbiologistESCO 2131.4.9Overlapping, not the same
Microbiologists study and research the life forms, characteristics, and processes of microscopic organisms. They study microorganisms such as bacteria, protozoa, fungi, etc. in order to diagnose and counteract the effects that these microorganisms might have in animals, in the environment, in the food industry, or in the health care industry.
