Suggestibility suppression
Suggestibility suppression can be described as a decreased tendency to accept and act on the suggestions of others. A common example of suggestibility depression in action would be a person being unwilling to believe or trust another person's suggestions without a greater amount of prior discussion than would usually be considered necessary during every day sobriety.
Although this effect can occur as a distinct mindstate, it is can also often arise due to interactions between a number of other effects. For example, a person who is currently experiencing mild paranoia combined with analysis enhancement may find themselves less trusting and more inclined to think through the suggestions of others before acting upon them, alternatively, a person who is experiencing ego inflation may find that they value their own opinion over others and are therefore equally less likely to follow the suggestions of others.
Suggestibility enhancement is most commonly induced under the influence of moderate dosages of stimulant compounds, particularly dopaminergic stimulants such as methylphenidate, amphetamine, and cocaine.
