“Suggestion” is the psychological process by which one person guides the thoughts, feelings, or behaviour of another. Predominantly used in therapeutic and clinical settings, suggestions can be categorised into two types: direct and indirect. Direct suggestions are explicit proposals for a person to think or behave in a certain way – commonly employed in hypnosis. Conversely, indirect suggestions are more subtle, often embedded within metaphorical narratives or storytelling. Despite their prevalence in everyday communication, suggestions remain subject to controversy due to their ability to manipulate perception and influence decision-making – both ethically concerning areas. Notably, they have found applications across various fields including medicine (hypnotherapy), advertising (subliminal messaging), and law (leading questions).
