Have you ever heard of a placebo? The word “placebo” comes from Latin, meaning “I will please.” But what exactly does it do, and does it really work?
Imagine you’re feeling sick, and your doctor gives you a pill. This pill might not have any active ingredients to treat your illness, but it can still make you feel better. How? This is known as the placebo effect. It’s not the pill itself that helps; it’s your belief that it will make you feel better. This belief can actually lead to real changes in how you feel.
The placebo effect is linked to something called classical conditioning, which is a bit like training your brain. It’s similar to the famous experiment with Pavlov’s dogs, where the dogs learned to associate a bell with food. In the case of placebos, your brain learns to associate taking a pill with feeling better.
There’s also a concept called subject expectancy. This means that if you expect to feel better, your brain might actually change how you react to your symptoms, making you feel better.
Placebos can be anything from sugar pills to vitamins or even antibiotics. Doctors might use them when a patient is in pain or tired, and there’s no specific treatment available. Sometimes, if a patient insists on getting treatment that the doctor thinks isn’t necessary, a placebo might be given instead.
A study published in the journal PLOS ONE found that placebos are quite common. In the UK, about 97% of doctors have given placebos at least once in their careers. In the US, it’s about half of the doctors.
Before you worry about getting a sugar pill instead of real medicine, consider this: placebos can actually affect your brain. A study from the University of Michigan in 2004 showed that when patients were told a placebo was a painkiller, their brains released endorphins, just like when they took real pain medication. This means that placebos can trigger the brain’s natural pain relief system.
Knowing that you might not always be getting real medication, how does that make you feel? Some people find it fascinating. If a placebo makes you feel better without the side effects of real drugs, it might be a good thing. Plus, it can help reduce the use of antibiotics, which is important for preventing antibiotic resistance.
Others see it as a form of mental treatment rather than a physical one. It can work well unless it doesn’t, in which case it might not be ideal.
What do you think about placebos? Do you find them interesting or concerning? Share your thoughts and connect with others to learn more about the fascinating world of science!
Design a simple experiment to test the placebo effect. You could use candy labeled as “energy boosters” and observe if participants feel more energetic after consuming them. Record your observations and discuss the results with your classmates.
Pair up with a classmate and take turns playing the roles of doctor and patient. The “doctor” should explain the concept of a placebo to the “patient” and discuss when it might be used. Reflect on how this conversation might affect a patient’s perception of their treatment.
Research classical conditioning and its connection to the placebo effect. Create a short presentation or poster that explains this concept using examples, such as Pavlov’s dogs, and share it with the class.
Engage in a class debate about the ethical implications of using placebos in medical treatment. Consider arguments for and against their use, and discuss how transparency with patients might affect the outcome.
Think about a time when you felt better after taking medication or receiving treatment. Write a reflection on whether you think the placebo effect might have played a role in your experience, and share your thoughts with the class.
Sure! Here’s a sanitized version of the transcript:

You guys have heard of placebos, right? Placebo is Latin for “I will please.” But does it really work?
Hey everyone, welcome to DNews! I’m Lacy Green, and I’m Trace. Placebo is a medicine or procedure that isn’t proven to treat your illness but can make you feel better. When it comes to the placebo effect, the drug itself isn’t important; what makes it work is that we’re conditioned to believe that taking pills makes us feel better, so we do feel better.
In more technical terms, this is known as classical conditioning, similar to Pavlov’s dogs. There’s also a related concept called subject expectancy, where we expect to feel better, leading us to unconsciously change our reactions to our symptoms.
Common placebos include sugar pills, aspirin, vitamin and mineral supplements, or antibiotics. They are often used when a patient is in pain or experiencing fatigue, and there’s no treatment available, or if they insist on receiving treatment that the doctor believes is unnecessary.
A study published in the journal PLOS ONE reveals that placebos are quite common; about 97% of doctors in the UK admitted to giving placebos instead of medication at least once in their careers. In the US, it’s about half.
Before anyone in the US gets concerned about the cost of sugar pills, there are two important points to consider: First, our healthcare system is very different from the UK’s National Health Service, which is publicly funded, making it less burdensome to receive care. Second, placebo pills can be effective because they actually have an impact on the brain. A 2004 University of Michigan study showed that patients who were told a placebo was a painkiller responded similarly to those who received real pain medication, as their brains released the same endorphins.
So, how does that make you feel, knowing you might not be getting real medication for your aches and pains?
I think it’s interesting. If a doctor prescribes me a pill and it makes me feel better, who am I to question its contents? If I feel better at the end of the day and avoid taking antibiotics that could contribute to antibiotic resistance, then I’m okay with it.
I feel similarly. It’s still a form of medication; it’s more of a mental treatment than a physical one. It can solve the problem unless it doesn’t, and then it wouldn’t be ideal.

Placebo – A substance or treatment with no active therapeutic effect, often used in experiments to test the effectiveness of a new drug – In the study, one group received the actual medication, while the other group received a placebo to compare the results.
Effect – A change that is a result or consequence of an action or other cause – The effect of the new teaching method was evident in the students’ improved test scores.
Brain – The organ in the head that controls thoughts, memory, feelings, and activity – Scientists are studying how different parts of the brain are involved in processing emotions.
Belief – An acceptance that something exists or is true, especially without proof – Her belief in her ability to succeed helped her overcome many challenges.
Treatment – The management and care of a patient to combat a disease or condition – The doctors decided on a new treatment plan to help manage the patient’s symptoms.
Pain – An unpleasant sensory and emotional experience associated with actual or potential tissue damage – The patient reported a decrease in pain after starting the physical therapy sessions.
Study – A detailed investigation and analysis of a subject or situation – The study revealed new insights into how sleep affects memory retention.
Symptoms – Signs or indications of a condition or disease – The doctor asked about her symptoms to determine the best course of action.
Conditioning – A learning process in which an individual learns to associate a specific stimulus with a particular response – Pavlov’s experiments with dogs are famous examples of classical conditioning.
