Communication is the very basis of human connection, which helps to build our relationships, talk among pals, and get our work done across daily lives. Yet, it is not surprising to know how many of us underestimate, much of what we understand and convey actually goes far beyond the total words we speak.







Imagine if we were to talk to each other so plainly, without using any expressions or body language at all. It would not only be a monotonous show but also would fail to convey what we actually mean, and might create confusion too.





Similarly, in even the most important days of our lives, like an interview or a romantic proposal, our body language actually does more hidden magic than we do with our words.





Secret rule to ace a conversation



Successful communication, especially in emotionally charged or high-stakes settings like job interviews, depends heavily on these unspoken cues. Understanding and mastering this dimension of communication is essential for anyone looking to build strong connections and convey truth and honesty.







The 7-38-55 rule : What it means



Nearly 50 years ago, psychologist Albert Mehrabian introduced a model that explains how people interpret feelings and attitudes during face-to-face communication.





According to Mehrabian’s research, only 7% of the emotional meaning in communication comes from the words used. In contrast, 38% comes from the tone of voice, and a significant 55% from body language such as facial expressions and gestures. This “7-38-55 rule” tells that when words conflict with tone or body language, people tend to trust the nonverbal cues more than the actual spoken words.





This explains why we can perceive a mismatch when someone says they are fine, but their tone or posture suggests otherwise. It’s a reminder that communication is much more than just the verbal content, it’s the total package of how something is said and the cues we send unconsciously.









Is it really the tool to crack job interviews?





Entrepreneur and author Ankur Warikoo recently highlighted the importance of the 7-38-55 rule in job interviews. He pointed out that many candidate failures are not about what they say but how they say it and the presence they project. In his popular LinkedIn post, Warikoo explained the rule and told how emotional presence, which is expressed through tone and body language, often outweighs even perfectly formed answers.





To crack interviews, Warikoo advises candidates to record themselves practicing to monitor tone, eye contact, and posture. He stresses the need for alignment between body language, voice, and words.





He practically advised people to include entering calmly, greeting confidently, speaking with warmth and clarity, using natural gestures, maintaining open body language, and practicing under real conditions to build confidence.









Applying it beyond interviews





The lessons of the 7-38-55 rule extend far beyond interviews into everyday communication and leadership. When interacting with others, especially in situations where emotions or feedback are important, it’s crucial to be aware of the entire communication package we send to the perceiver.





This rule also reminds us to be attentive listeners, not only to words but to the accompanying vocal and physical cues. It is also important to identify and keep a watch when words don’t align with nonverbal signals, helping us to respond more empathetically and effectively.







How to apply the rule in real life

• Record yourself answering interview questions to improve your tone, eye contact, and posture.


• Enter the room calmly, shake hands firmly, sit upright, and keep the body language open.


• Control the tone by speaking clearly, varying the pace and pitch, and projecting warmth.


• Use natural gestures and open palms, with soft and confident facial expressions to emphasise points.


• Rehearse under realistic conditions, prepare like a full mock interview to build confidence.
