Document Summary
The more we come to appreciate why our beliefs might be true, the more tightly we cling to them. Once we have explained to ourselves why we believe a child is gifted or has a specific learning disorder, we tend to ignore evidence undermining our belief. Once beliefs form and get justified, it takes more compelling evidence to change them than it did to create them. Framing the way we present an issue sways our decisions and judgments. One tells patients that 10 percent of people die during this surgery. Although the information is the same, the effect is not. Both patients and physicians perceive greater risk when they hear that 10 percent die. Similarly, 9 in 10 college students rated a condom as effective if told it had a supposed 95 percent success rate in stopping the hiv virus. 10 judged it effective when told it had a 5 percent failure rate (linville et al. , 1992).
