To determine whether the given statement is true or false, and if false, to provide the correct reasoning:

### Statement to be evaluated:
"A double-blind experiment is used to increase the placebo effect."

### Step-by-Step Analysis:

1. Understand What Double-Blind Means:
- In a double-blind experiment, neither the participants nor the experimenters know who is receiving a particular treatment. This methodology is employed to prevent bias in research results.

2. Understand the Placebo Effect:
- The placebo effect occurs when participants experience changes in their condition simply because they believe they are receiving an active treatment, even if it is just a placebo.

3. Purpose of Double-Blind:
- The purpose of a double-blind experiment is to eliminate biases and ensure the reliability of the results by making sure that the participants' and researchers' expectations do not influence the outcomes of the study.

### Conclusion:

- The statement claims that double-blind experiments are used to increase the placebo effect.
- However, the correct reasoning is the opposite. Double-blind experiments aim to decrease the placebo effect by preventing participants' and researchers' expectations from influencing the results.

Thus, we rewrite the statement as:
"A double-blind experiment is used to decrease the placebo effect."

### Correct Answer:
OB. The statement is false. Double blinding is used to decrease the placebo effect.
