What indicates a proper investigation method?

Using a scientific method to ensure accuracy is a crucial indicator of a proper investigation method. The scientific method provides a systematic approach that prioritizes objectivity, repeatability, and integrity in the investigative process. This involves formulating a hypothesis, gathering evidence, analyzing data, and drawing conclusions based on empirical findings. By adhering to this structured methodology, investigators can minimize biases and ensure that their conclusions are based on reliable evidence, thereby enhancing the credibility and validity of the investigation.

In contrast, relying solely on personal experience can lead to subjective interpretations that may overlook important evidence or alternative explanations. Ignoring conflicts of interest compromises the integrity of the investigation by introducing potential biases and undermining public trust. Additionally, documenting findings without peer review lacks the necessary checks and balances that help to validate the investigation's conclusions, reducing the likelihood of overlooking critical details or making unfounded claims. Overall, employing the scientific method is fundamental in maintaining the rigor and reliability expected in fire investigations.
