Investigation vs. research: what’s the difference?
The short answer
An investigation is usually a formal inquiry into a specific event, situation, or crime, often aimed at finding evidence or answering specific questions. It implies a narrower focus and is often associated with legal or official contexts. Research, on the other hand, is a broader term that refers to the systematic study of a topic or phenomenon to establish facts, reach new conclusions, or develop theories. It is often used in academic or scientific contexts and implies a more general pursuit of knowledge.
What they have in common
Both investigation and research involve a systematic process of inquiry and examination to discover facts or gain information.
