Abductees
The precise number of alleged abductees is uncertain. One of the earliest studies of abductions found 1,700 claimants, while contested surveys argued that 5–6 percent of the general population might have been abducted.
As a category, some studies show that abductees have psychological characteristics that render their testimony suspect. Dr. Elizabeth Slater conducted a blind study of nine abduction claimants and found them to be prone to "mildly paranoid thinking," nightmares and having a weak sexual identity.
According to Yvonne Smith, some alleged abductees test positive for lupus, despite not showing any symptoms.
