Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.

### Instruction:
Propose a hypothesis to explain this observation.

### Input:
Recent studies have found that greater outside temperature leads to increased aggression in humans.

### Response:
The hypothesis is that increased heat leads to higher levels of aggression perhaps due to a decrease in people's ability to self-regulate emotions in warmer environments. Additionally, increased outside temperatures can put people in a more negative emotional state, which can lead to aggression.
