Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Evidence from animal and human studies consistently indicates that prolonged extreme social isolation, such as solitary confinement, leads to predictable psychological deterioration and mental health problems.

The analysis

The claim that prolonged extreme social isolation causes predictable psychological deterioration is specific and falsifiable. Retrieved papers examining solitary confinement and extreme social isolation (such as papers 1, 2, 7, and 10) provide clear empirical and clinical evidence demonstrating significant adverse psychological and psychiatric consequences. Therefore, the balance of evidence strongly supports the claim.
