Answer: The field of Parapsychologists.
Explanation:
The type of words used above as well as the tone suggests that the author does not think highly of the field of parapsychologists. Indeed, in calling the field fraudulent, the author is actively looking down on the field.
The author is therefore showing bias against the field because the author includes no positives about the field. The text is singularly garnered at making the reader think lowly of the field as well. The author is therefore biased in their analysis of the field which means they are biased against the field in general.
