Have you ever had a conversation where you’re convinced the other person isn’t taking in what you’re saying, not by words but by their non-verbal cues?

A body language expert has shared insights into how to tell if someone is actually agreeing with you during a conversation. Adrianne Carter, known for her ability to “read” people, gave some advice on spotting this specific behaviour which has caused quite a stir on TikTok, garnering over four million views.

Demonstrating with her left hand beneath her chin and her index finger pointed up by her ear, Adrianne advised in her clip: “Notice where my hand and my finger is on my face – you might see this in a meeting or when you’re interacting with someone – they’re thinking about what you’re saying.”

She further suggested that when the finger creeps higher along the side of the face, it signals that “they’re thinking, but also not really approving or liking what has been said”. Wrapping up her video, Adrianne noted: “So watch for that finger – and how far it goes up the face.”

The tip hit home with one of her 626,000 followers who admitted: “This is super true for me,” realizing “I never thought about it before, but this is totally me.” Another noted: “They do that a lot of this on Dragons’ Den. I can’t wait to watch another episode and try to anticipate their vote.”

A third TikTok user confessed: “I was doing this this morning and yes you are right, I wasn’t liking what that person was saying.” Meanwhile, a fourth shared: “This is really interesting, because I do this, and I’m thinking back and like recognising that I do this in my finger gets higher when I’m irritated or disagree with what is being said.”

However, some users were sceptical of the advice, arguing against generalisations. “This is not accurate,” one TikTok user commented. “Body language is not universal. We need to look for changes in baseline not infer reasons behind movement.”

A second individual echoed the sentiment, arguing: “Not true! You can’t generalise hand/finger placement like that.” Whilst a third added: “Disagree. I do this if I’m getting nervous, but it has nothing to do with me not approving something or not.”

Adrianne also took to the comments section to detail her expertise, stating: “I trained in facial expressions, FACS (Facial Action Coding System) – and fully qualified 12 years ago. Trained in body language with top 10 trainer in the world.”

On her website, meanwhile, she further elaborates on her credentials: “Over the years, I’ve worked with clients from all over the world, including household names like Apple, Coca-Cola, and The National Trust. I’ve also been a guest lecturer in consumer psychology and behavioural economics at several UK universities.”
