Question: Describe how the belief in calorie-reducing diets as an effective long-term treatment for obesity serves as an example of motivational bias. In your explanation, state what scientific research reveals about this belief, and recall the specific psychological factors that lead people to persist in it despite the evidence.
Sample answer: The belief that calorie-reducing diets are an effective long-term treatment for obesity represents a motivational bias because people continue to hold this belief despite scientific evidence contradicting it. Scientific research shows that calorie-reducing diets are actually not an effective long-term treatment for obesity. Individuals persist in this belief because it serves psychological needs: it offers hope for weight loss to those who want to lose weight, and it makes people feel good about exhibiting self-control.
Key points:
- State that the belief in calorie-reducing diets as an effective long-term treatment for obesity is an example of motivational bias.
- Recall that scientific evidence contradicts the effectiveness of calorie-reducing diets for long-term obesity treatment.
- Explain that people persist in this belief because it offers hope for weight loss.
- Explain that people persist in this belief because it makes them feel good about exhibiting self-control.
Rubric: The answer must recall the core concept of motivational bias by explaining that the belief persists despite scientific evidence to the contrary. It must state that scientific research contradicts the long-term effectiveness of these diets. Finally, it must recall the two motivational drivers: providing hope for weight loss and generating positive feelings about exhibiting self-control.
