The girls often act in ways that are not typical of those who are truly possessed. For example, they are able to control their movements and speech, and they are not afraid of holy objects. They also seem to enjoy the attention they are getting from the trials, and they are willing to accuse innocent people in order to maintain their status.
The girls' accusations are based on hearsay and speculation.
The girls often accuse people of witchcraft based on what they have heard from others, or on their own suspicions. They do not have any concrete evidence to support their claims, and they are often unable to provide details about the alleged crimes.
The girls are influenced by their social and economic circumstances.
The girls who are accused of witchcraft are often from poor and marginalized families. They may be seen as a threat to the social order, and they may be targeted for persecution as a way to control them.
The girls are motivated by personal grudges.
Some of the girls who are accused of witchcraft may have personal grudges against the people they accuse. They may be seeking revenge for real or perceived slights, or they may be trying to deflect attention from their own misdeeds.
These factors all suggest that the girls in the Crucible are not really bewitched, and that their accusations are based on a combination of factors, including social, economic, and psychological pressures.
