To be committed, the evidence must demonstrate that the person in question has serious difficulty controlling his behavior, and evidence of psychopathy is frequently introduced in these cases. However, some have voiced concern that there is no guidance regarding how to define or assess volitional control, that experts often reach different conclusions in these cases, that predicting future behavior is difficult to assess, and that evidence of psychopathy might bias the factfinder. The current study examined whether a psychopathy diagnosis or the presence and content of expert testimony regarding these concerns would influence participants’ sentencing decisions and attitudes about the person on trial.
