Why must researchers keep their own expectations from influencing their experiments?

An experiment is an arrangement or a set up of various instruments that gives results on the basis of given condition.

The results of en experiment may and may not be exact the same as one must have thought because various parameters comes into role while performing an experiment hence researchers should keep their expectations to there own.

This influence can degrade the accuracy of an experiment as expectation might not match the final product.

To improve accuracy

Explanation:

Willpower for one side of an argument, or bias, may lead to altered results, incorrect experimentation and an incorrect outcome. While it is important to form a hypothesis at first, a researcher should never let their expercations interfere in the scientific process.
