Ford is considering driving his car onto a lake that appears to be frozen, but may not be safe. he thinks to himself, "only dummies fall through the ice in their cars, and i am no dummy, so i will drive on the ice even though i am not sure it’s safe." ford’s decision best exemplifies the concept of

an illusion of invulnerability.

3. Morality.

4. Stereotypes.

5. Pressure.

6. Self-censorship.
