Placebo effect
Definition
The placebo effect describes the phenomenon where a person experiences an improvement in their health condition despite receiving a treatment that has no therapeutic effect – such as a sugar pill, an ineffective procedure, or a sham treatment. The effect occurs due to the belief or expectation of the affected person that the treatment will be effective. In medical research, the placebo effect is often used as a control group in studies to measure the actual effect of a drug or procedure.
The placebo effect is based on psychological and physiological processes, with the patient's belief playing a significant role. In neurology and psychology, it is seen as evidence that the human mind can have a significant influence on physical processes.
Origins and Theoretical Background
The term 'placebo' comes from Latin and means 'I will please', which originally had the meaning of pleasing or comforting someone. The placebo effect was first observed in modern medical practice in the 18th century when patients in clinical trials reported improvements that could not be attributed to any real effect of the treatment.
In NLP, the placebo effect is considered an example of the power of belief and internal representations. Bandler and Grinder, the founders of NLP, recognized that the belief in a positive change often constitutes the largest part of the healing process. They developed methods to help clients manage their internal beliefs and expectations in a way that allows them to bring about positive changes in their lives.
Application Examples
- Pain Management: A client who regularly suffers from pain might experience relief from their discomfort simply by the belief that they are taking a 'magic' pill (which is actually just a placebo) – solely based on the expectation that the treatment works.
- Improvement of Self-Confidence: In a coaching scenario, a client might actually experience an increase in their self-confidence and social skills through positive beliefs and the notion that they have an effective 'therapy' available.
- Treatment of Fears: A person with a fear of flying might reduce their anxiety by trusting in a technique or treatment declared to be 'particularly effective' (which actually has no effect), solely based on the expectation that they are now better able to fly.
Areas of Application
- Therapy: Utilizing the placebo effect to enable clients to improve their symptoms through positive expectations.
