Hello. I have often observed individuals, both professionally and personally, will end a statement with a laugh (usually a nervous one). Over decades of professional engagements, I have come to the conclusion that this behaviour is usually due to the person speaking beyond their knowledge or competency, or "daring" to be challenged on their interpretation of a situation; as if they want their view to become the accepted view.
I am curious as to others views on this.
Much appreciated.
