Main Difference
The main difference between Opinion and Suggestion is that the Opinion is a judgment, viewpoint, or statement that is not conclusive; may deal with subjective matters in which there is no conclusive finding and Suggestion is a psychological process by which one person guides the thoughts, feelings, or behavior of another person
Opinion
In general, an opinion is a judgment, viewpoint, or statement that is not conclusive. It may deal with subjective matters in which there is no conclusive finding, or it may deal with facts which are sought to be disputed by the logical fallacy that one is entitled to their opinions. What distinguishes fact from opinion is that facts are more likely to be verifiable, i.e. can be agreed to by the consensus of experts. An example is: “United States of America was involved in the Vietnam War” versus “United States of America was right to get involved in the Vietnam War”. An opinion may be supported by facts and principles, in which case it becomes an argument. Different people may draw opposing conclusions (opinions) even if they agree on the same set of facts. Opinions rarely change without new arguments being presented. It can be reasoned that one opinion is better supported by the facts than another by analyzing the supporting arguments. In casual use, the term opinion may be the result of a person’s perspective, understanding, particular feelings, beliefs, and desires. It may refer to unsubstantiated information, in contrast to knowledge and fact.
Collective or professional opinions are defined as meeting a higher standard to substantiate the opinion. (see below)
Suggestion
Suggestion is the psychological process by which one person guides the thoughts, feelings, or behavior of another person.
Nineteenth-century writers on psychology such as William James used the words “suggest” and “suggestion” in the context of a particular idea which was said to suggest another when it brought that other idea to mind. Early scientific studies of hypnosis by Clark Leonard Hull and others extended the meaning of these words in a special and technical sense (Hull, 1933).
The original neuropsychological theory of hypnotic suggestion was based upon the ideomotor reflex response that William B. Carpenter declared, in 1852, was the principle through which James Braid’s hypnotic phenomena were produced.
