Stuttering does not affect and has no bearing on intelligence. Apart from their speech impairment, people who stutter are generally normal in every other way. Anxiety, low self-confidence, nervousness and stress do not cause stuttering. Very often it`s the other way round and those things are the result of living with a highly stigmatized disability. You can help to change this. If you meet someone who stutters, just act normal. Maintain eye contact, allow to finish speaking and add no words. It`s that simple. Just give everyone the time they deserve.
German Stuttering Association have released this witty campaign recently. The videos will have a glitch, don`t worry. The creatives have made an Uploading effect, which is supposed to demonstrate how does it feel talking to a stuttering person. The company is asking for patience and understanding.
