The best method to control placebo effects in both subjects and experimenters is to use a double-blind study design. In this approach, neither the participants nor the researchers administering the treatment know who is receiving the actual treatment and who is receiving a placebo. This helps to minimize biases and expectations that could influence the outcomes. Additionally, using standardized measures and ensuring that all participants have similar interactions can further reduce the impact of placebo effects.

A placebo is used in an experiment as a control. For example, when testing a new medication, experimenters will split the group in two- a control group and an experimental group. The experimental group receives the actual medication, while the control group receives a placebo (in this case, a sugar pill). The placebo will not have any actual effect on the person, but is meant to make sure people aren't making themselves believe that they are cured.

I want to know if a medication has the desired effect. I'm going to give half the subjects the 'live' med, and half will get a placebo. The subjects will not know which one they are getting. That's one level of "blind". Studies show that there is a measurable affect based on the fact that the person distributing the med's knows who is getting the med and who is getting the placebo. So I am going to package the med's and give them to the distributing nurse, and the nurse will not know who is getting the med and who is getting the placebo. That is "double blind" model.
The group that receives no treatment in an experiment is called the control group. This group is used as a point of comparison to evaluate the effects of the treatment applied to the experimental group.
If the experimenters know but the subject does not, it's called a "single blind" study. If the placebo is randomized and neither the subject nor the experimenters know which is the placebo, it's called a "double blind" study.
I think the things they have in common is how many of the things that the placebo and nocbo all are psychological. and the supject can not experance the placebo and novebo with out them knowing or having an idea of what is happaning( or the idea can form in there mind), If you give someone a sugur pill the only effect related to the pacebo effect to happen are all in the mind and what the subject thinks it is.
An unobtrusive observation is when an experimenter simply watches and takes notes of the behavior of the subject in either a natural or laboratory setting WITHOUT any kind of interaction between the experimenter and subject.This is the opposite of an obtrusive observation in which the experimenter DIRECTLY interacts with the subject. For example, in a social environment, the experimenter makes eye contact and smiles at an individual walking by to watch for a response. In an unobtrusive observation, the experimenter would simply watch the way the subject responds to other people but DOES NOT deliberately smile to watch for a response.
This is what i found on this subject: "I'm on Yaz for 9 months now and i always start getting my period by the 3rd day of the placebo pill."
A placebo is a treatment, most commonly a medication of some kind, which is given to a subject with the pretense that it will treat a specific ailment when in fact the treatment will have no significant effect on the subject. The subject may report that the treatment has had a positive effect, when in fact the effect is entirely in the imagination of the subject. Therefore, a placebo variable is a factor that researchers in the medical field must consider when experimenting with new treatments, to decide whether the success of the treatment is due to the psychological or placebo effect of the treatment, or if the treatment itself is working.
