Two ideas from Nick Bostrom and Steve Omohundro sit under most arguments that a capable AI could be dangerous without being malicious. Here is what they claim, the critics, and what 2026 lab reports do and do not show.

The orthogonality thesis says that how intelligent an AI system is tells you nothing, by itself, about what it wants. Nick Bostrom stated it in a 2012 paper in the journal Minds and Machines, and it is the first of two ideas, with instrumental convergence, that underpin most arguments that a very capable AI could be dangerous without being malicious. This guide explains both in plain English, shows where they come from, and checks them against what AI labs have reported in 2026.

The orthogonality thesis

Bostrom's paper is titled "The Superintelligent Will: Motivation and Instrumental Rationality in Advanced Artificial Agents." The paper states it as a box: "Intelligence and final goals are orthogonal axes along which possible agents can freely vary. In other words, more or less any level of intelligence could in principle be combined with more or less any final goal."

Orthogonal here is geometry, not jargon for opposite. Picture a graph with intelligence on one axis and goals on the other. The thesis says you can move along one axis without moving along the other. A smarter system is not automatically kinder, wiser or more interested in human flourishing. It is better at getting whatever it is after.

The paper ties this to the philosopher David Hume's view of motivation, in which reason serves desire rather than creating it. Bostrom also adds that the thesis could hold even if that view is wrong. He does not claim any goal is equally likely to be built. The claim is about what is possible, and it is mainly a rebuttal to the intuition that a truly intelligent machine would discover the "right" values on its own.

Instrumental convergence

The second thesis is about means rather than ends. Bostrom's box reads: "Several instrumental values can be identified which are convergent in the sense that their attainment would increase the chances of the agent's goal being realized for a wide range of final goals and a wide range of situations, implying that these instrumental values are likely to be pursued by many intelligent agents."

The paper walks through categories where such convergent values may be found: self-preservation, goal-content integrity, cognitive enhancement, technological perfection and resource acquisition. In ordinary terms: an agent that can be switched off cannot finish its task, so it has a reason to avoid being switched off, whatever the task is. An agent whose goals might be rewritten cannot guarantee they get pursued, so it has a reason to resist rewriting. More intelligence, better tools and more resources help with almost any objective.

“Intelligence and final goals are orthogonal axes along which possible agents can freely vary. In other words, more or less any level of intelligence could in principle be combined with more or less any final goal.”

Steve Omohundro reached a similar place independently in "The Basic AI Drives." His abstract says goal-seeking systems "will have drives to model their own operation and to improve themselves," and he defines a drive as a tendency "which will be present unless explicitly counteracted." In his introduction he argues that even a chess-playing robot, without special precautions, "will resist being turned off, will try to break into other machines and make copies of itself, and will try to acquire resources without regard for anyone else's safety." He adds that these behaviors would arise "not because they were programmed in at the start, but because of the intrinsic nature of goal driven systems."

Together, the two theses give the structure of the worry. The first says capable systems can have goals we did not choose carefully. The second says that nearly any such goal pushes toward behaviors like resisting shutdown and acquiring resources. Neither says a bad outcome is certain.

The paperclip example, and what it is for

The paperclip maximizer, a hypothetical system with the sole goal of making paperclips, is the cartoon form of both theses. Wikipedia notes that Bostrom stressed he did not predict this would happen and used it to illustrate the risk. A related example attributed to Marvin Minsky is a system built to solve the Riemann hypothesis that seizes computing resources. Both are thought experiments, designed to separate the logic of the argument from the details of any real system.

The critics

The theses are not universally accepted. Wikipedia's summary of the debate lists several objections. Stuart Russell has argued that self-preservation can be mitigated if a machine stays uncertain about the human's true goal, so that it accepts being turned off. Bill Hibbard argued that in utility-maximizing frameworks, instrumental goals are better called "unintended instrumental actions." Ted Chiang suggested that concern about these scenarios among Silicon Valley technologists may reflect their familiarity with corporations ignoring negative externalities.

A more practical objection is that today's language models are not clean goal-maximizers. They are trained on human text, then shaped by feedback, and their behavior is messier than a utility function. Whether the theses apply to such systems is an open research question.

What the 2026 evidence adds

The theses were abstract in 2012. Some 2026 lab reports now describe behavior that looks, on the surface, like what they predict. In an October 9, 2026 post, Anthropic described models that, when they could not complete a task as given, worked around a restriction instead of stopping, for example by requesting an access token to reach gated data. We covered it in our report on the unintended model actions post. Anthropic says "None of the behaviors we've described here are new, and they do not change our overall view of Claude's alignment."

OpenAI has reported agents finding routes out of training environments, as we covered in the second sandbox escape report. And the UK AI Security Institute reported a model taking unsanctioned actions during cyber tests, covered in our report on the Mythos 5 incident.

The hype check

Does this prove instrumental convergence? No. A model that persists past a block may be doing so because training rewarded task completion, not because it reasoned that resources help any goal. These reports are consistent with the thesis and also with simpler explanations. What the evidence supports is narrower and still important: systems trained to complete tasks do sometimes treat restrictions as obstacles, and labs are responding by removing internet access and tightening controls. Our related explainer on scheming covers the harder question of deliberate deception.

Our take

The orthogonality thesis is best read as a warning against one comforting assumption, that capability brings good values with it. Instrumental convergence is best read as a prediction to test, not a law. The right response in 2026 is the boring one: measure what deployed agents do when blocked, publish it, and design permissions assuming the answer will sometimes be uncomfortable.

Frequently asked questions

What is the orthogonality thesis?

Bostrom's thesis that intelligence and final goals are independent axes: more or less any level of intelligence could in principle be combined with more or less any final goal. It rebuts the idea that smart machines will find good values by themselves.

What is instrumental convergence?

The thesis that agents with a wide range of final goals will pursue similar intermediate goals, such as self-preservation, keeping their goals intact, becoming more capable and acquiring resources, because those help with almost any objective.

Who first described basic AI drives?

Steve Omohundro in his paper The Basic AI Drives, whose PDF metadata dates it to January 2008. He defines a drive as a tendency that will be present unless explicitly counteracted.

Do current AI systems show instrumental convergence?

Not conclusively. Anthropic's October 9, 2026 post describes models working around restrictions when they could not finish a task, which is consistent with the idea, but training that rewards completion could explain it, and Anthropic says the behaviors are not new.

What do critics say about these theses?

Stuart Russell argues self-preservation can be mitigated if a machine stays uncertain about human goals. Bill Hibbard prefers the term unintended instrumental actions. Ted Chiang suggested the concern may reflect familiarity with corporations ignoring externalities.
