It is unrealistic to expect people to keep track of the original basis of their beliefs, and to revise a belief when its original basis is undercut. The statements originally given to the subjects would be highly misleading even if true. Most of the subjects were initially skeptical of the statements originally given to them. Most of the subjects had acquired confirmation of their newly acquired beliefs by the time they were told that the original statements were false.
Journal: In several psychological studies, subjects were given statements to read that caused them to form new beliefs. Later, the subjects were told that the original statements were false. The studies report, however, that most subjects persevered in their newly acquired beliefs, even after being told that the original statements were false. This strongly suggests that humans continue to hold onto acquired beliefs even in the absence of any credible evidence to support them.
Which one of the following, if true, most undermines the journal's argument?
