Punctuating statements with a nervous laugh

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.

Hi, chaos, and welcome to Psych Central! I've not observed that behavior enough to draw conclusions, but the thought I have across the top of my head is maybe the person is also concerned that someone will disagree with what they said.

I have someone in my life like that. I think she may have narcissistic personality disorder. Her husband's family loves to laugh. I believe she's mimicking their behavior by laughing at the end of her statements, even though she's not saying anything funny. I think she's very insecure.

It could be anxiety or hundred other things. Nervous laugh is quite common. I don’t think it’s anything sinister or malicious

It based on fear of being accused or judged.

When a person asks me a pointed question and the answer is so obvious I laugh. It's like the hit the nail on the head. Other times when some-one else is sharing their own experiences and I can totally relate to the similarity then I can laugh. Not because anything is funny but more because I understand it. Once I laughed when a person had shared an experience that wasnt funny but relatable. She told me that it wasnt funny and I said that I knew it wasnt funny I just understood where she was coming from. Since then I try to temper my response and am on the front foot explaining my reaction.

I do it. It's a social anxiety issue for me. I'm trying to curb it.

I’ve done it on occasion. It’s that I’m telling someone something and realize as I’m saying it that it’s embarrassing or pointless. I’ve also done it when something really serious has happened and I have to repeat it, but I nervously laugh because it was so awful, like a reverse reaction, but not... like my friend’s dog was eaten by a gator.
