Beyond All Possible Doubt? The Shifting Of A Juror’S Conviction Threshold In Criminal Cases Based On Charge, Sentence, And Evidence, Sophie Johnson

Theses and Dissertations

In criminal trials, jurors must make a decision that will forever change the defendant’s life (Couloute & Kopf, 2018), during which jurors may consider the impact that not convicting a guilty person may have (i.e., Type II error) or if the charge is worth the crime regardless of the defendant’s guilt (i.e., Type I error). Jurors may raise their conviction thresholds if they feel a type II error is favorable to a type I error. Researchers have discovered that in cases where charge severity (e.g., Kerr, 1978) or the perceived sentence (e.g., Kaplan & Krupa, 1986) is higher, jurors shift …
