Improving the Comprehensibility of a Canadian Police Caution on the Right to Silence

Modifications to a Canadian police caution on the right to silence were made in an attempt to increase its comprehensibility. University participants were asked to imagine themselves in an arrest and interrogation situation in which they were either innocent or guilty. It was hypothesized that participants who received the modified caution would score significantly higher on measures of comprehension than those who received the standard caution. Results indicated that comprehension was significantly higher among those that received the modified caution and that those with higher comprehension scores were more likely to exercise their right to silence. These findings suggest that clarifying and standardizing how a detainee’s rights are communicated will lead to better comprehension and greater protection against false or coerced confessions.
