What is one primary advantage of using simulations over real-world testing?

The primary advantage of using simulations over real-world testing is that it may be safer, cheaper, or faster than real-life testing. Simulations provide a controlled environment where complex scenarios can be modeled and tested without the dangers or high costs associated with actual experimentation. For example, in fields like medicine or engineering, simulations can allow practitioners to explore outcomes without putting anyone at risk, or they can help to quickly iterate on designs without the need for physical prototypes. This efficiency can significantly reduce both the financial expenditure and the time required for testing, making simulations a highly valuable tool in various domains.

Simulations also allow for the replication of scenarios that may be impractical or impossible to recreate in the real world, thereby providing insights that inform better decision-making and problem-solving. While it is not true that simulations eliminate all risks or are always more accurate than real-world tests, the balance of safety, cost, and speed make them a preferred method in many testing environments.
