Prejudices
Also professor of medical philosophy and ethics at Amsterdam UMC Guy Widdershoven thinks it is an interesting issue, and concludes that it does not matter for participating in a debate whether you are a patient yourself, or whether you have a family member who is. An interest in the subject and belief in a particular solution direction can be productive. But that is only part of the story. Bias, or prejudice, must be limited, according to Widdershoven.
He explains that it is precisely in the field of cognitive behavioral therapy that it has been investigated how bad it is when researchers believe in the therapy they have practiced and researched. 'That can be a bias that influences your objective view. It turns out that the bias exists but does not have to be a problem. It is good if you are interested in a problem and are motivated to find the solution in a certain direction. That is the vanguard that comes up with new scientific research. If you are negative and only interested in proving that something is not working, we will not get further into science, and you will not think up any potentially new creative solutions. '
