Hypotheses
Also written: Hypothesis generation
Educated guesses that scientists test to see if they are true.
Hypotheses are educated guesses that scientists make about how something works. They are based on existing knowledge or observations, but they need to be tested to see if they are correct.
For example, a scientist might hypothesize that a new drug will lower blood pressure. To test this, they would conduct experiments, perhaps with human volunteers, to see if the drug actually has that effect. If the results support the hypothesis, it strengthens the scientific understanding. If not, the hypothesis is revised or discarded, and new ones are formed.
A hypothesis is a testable statement that proposes a relationship between variables, serving as a starting point for scientific investigation. It is formulated based on prior observations, existing theories, or preliminary data, and is designed to be falsifiable through empirical evidence. The process of hypothesis testing is central to the scientific method, where data is collected and analyzed to either support or refute the proposed explanation.
In the context of AI research, hypotheses might concern the efficacy of a new model architecture, the impact of specific training data on performance, or the potential of an AI agent to solve a particular problem. For instance, researchers might hypothesize that a reinforcement learning agent trained with a specific reward function will outperform agents trained with other functions on a given task.
Frontier AI labs are increasingly used for scientific research, where forming and testing hypotheses is a core part of the process. AI models can help researchers generate new hypotheses or test existing ones more rapidly. This is particularly relevant as AI tools become more integrated into scientific workflows, accelerating discovery.

The concept of a hypothesis has roots in ancient Greek philosophy, particularly in the work of Aristotle, who discussed the role of assumptions in reasoning. It became a formalized component of the scientific method during the Enlightenment. Source ↗
Ask an AI chatbot like Microsoft Copilot or Anthropic's Claude to suggest a hypothesis for a simple experiment. For example, ask 'Suggest a hypothesis for why plants grow taller when exposed to more sunlight.' Then, ask it to outline a simple experiment to test that hypothesis.

Questions people ask
- What is the difference between a hypothesis and a theory?
- A hypothesis is a testable guess, while a theory is a well-tested explanation supported by a lot of evidence.
- Can AI generate hypotheses?
- Yes, AI can analyze data and suggest potential hypotheses that human researchers can then test.
