Final answer:
The foot-in-the-door phenomenon is exemplified by the fact that 76 percent of Californians agreed to install a huge ugly sign in their front yard after first being approached with a small request two weeks earlier.
Step-by-step explanation:
The fact that 76 percent of Californians agreed to install a huge ugly sign in their front yard after first being approached with a small request two weeks earlier exemplifies the foot-in-the-door phenomenon. The foot-in-the-door technique is a persuasive strategy where a person is first asked to agree to a small request or favor, and then later asked to agree to a larger request.
In this case, the small request was likely something simple like wearing a campaign button, which then made the homeowners more likely to agree to the larger request of putting campaign signs in their yard.
