と仮定して

と仮定して is used when the speaker deliberately assumes a condition that may not be true, and then logically considers the result based on that assumption.

The assumption is hypothetical, uncertain, or used only for reasoning.
The speaker does not claim the assumption is real — it is simply a tool for analysis or discussion.

This grammar is commonly used in:

• logical explanations

• academic writing

• business discussions

• problem-solving

• debates and reasoning

Unlike casual conditionals such as ～なら or ～ば, と仮定して sounds objective, analytical, and formal, and is often used when carefully examining consequences.
