Essay: The primary threats of validity

In most instances, the researchers are led by a specific objective to conduct their research. The experiments they carry out are meant to clarify what they already know theoretically to prove whether it is true or false. These people may dwell much on what they already know which can make them make controversial observations and eventually head to false conclusions that makes their research invalid.
