Humans have biases based on how they perceive things.

The Perception

We tend to stereotype things and events. Some stereotypes can be biological (e.g., men being physically stronger than women), some can be historical or statistical (e.g., credit systems or various forms of racism—though as a disclaimer, I am neutral and never consider race as a factor when connecting with people). Others are based on perceived “common sense,” such as assuming someone with a funny, entertaining tenor voice is less capable and lacks competence, while someone with a deep bass/baritone voice who is serious and never jokes is considered the opposite.

The Reason

I don’t know where this stems from. Perhaps a tenor voice creates a feeling of friendliness and an “out-of-work” environment, while a serious voice tends to raise people’s guard. Is this a product of human evolution and self-defense?

The Impact

Regardless, as the ones being perceived, how performant and capable we are judged to be is often affected by our tonal quality, how high-pitched we speak, and how much we joke and try to create a relaxed environment (which I am not sure is always a good thing), rather than how we actually perform. We are heavily accredited or discredited based on these superficial factors.

The Personal Experience

During a 1-on-1 with my director, he told me I ticked all the Technical Lead boxes except for one: “Tonal Quality,” which I still struggle to change today. I tend to create an easygoing environment where people feel comfortable talking and sharing. Consequently, I joke, smile, and rarely confront others. I approach conflicts very softly, and when things seem unsolvable, I simply delegate them to higher-level managers. This deeply affects how people perceive me as a Software Engineer—a role often stereotyped as needing to be “serious” and “nerdy” (I have literally received that exact comment). I have difficulty influencing people’s thoughts; they tend to talk down to me until they later realize my analysis was correct. I am not sure if this affects my interview evaluations, but I assume it does.

I know neither approach is inherently wrong, but it saddens me how much this society relies on intensity and seriousness as driving forces.

The resolution (copied from Gemini)

You don’t need to lose your warmth; you just need to develop what is often called “executive presence.” Here is how you can adjust your tone and communication style to be perceived more neutrally and authoritatively, without faking who you are:

1. Master the Downward Inflection

• People with friendly, higher-register voices often use “upspeak”—ending sentences on a higher note, which makes a statement sound like a question.
• The Fix: Practice ending your sentences with a downward inflection. It signals finality and confidence. When you say, “We need to refactor this module,” let your pitch drop on the word “module.”

2. Embrace the Pause (Stop Over-Filling Silence)

• When you naturally want to make people comfortable, silence feels like a threat. You might be filling pauses with nervous laughter, filler words, or small jokes to keep the energy light.
• The Fix: Say your piece, and then simply stop. Let the silence hang in the air. A well-placed pause communicates power, gives your words weight, and forces others to process your technical analysis instead of talking down to you.

3. Breathe from Your Diaphragm

• When we are eager to please or slightly anxious, we tend to breathe shallowly from our chests, which pushes the voice into a thinner, higher, more nasal tenor register.
• The Fix: Before a meeting, take a few deep breaths into your belly (your diaphragm). Speaking from your chest and stomach naturally lowers your pitch slightly and adds resonance, making your voice sound fuller and more grounded without sounding like you are faking a deep voice.

4. Separate the Person from the Problem

• You can absolutely be warm and friendly while still holding a firm line on technical conflicts. Right now, you are using softness and delegation to avoid the discomfort of confrontation.
• The Fix: Be soft on the people, but hard on the problem. You don’t have to stop smiling, but you can say, “I really appreciate your perspective on this approach. However, based on the performance metrics, we are going to go with Option B.” You do not need to joke to soften the blow. State it neutrally and move forward.

5. Save the Jokes for the Margins

• You don’t have to stop being an entertaining, pleasant person. Just change when you do it.
• The Fix: Be your funny, smiling self during the first 5 minutes of a meeting (the warm-up) and the last 2 minutes (the sign-off). But when you are analyzing a problem, presenting a solution, or dealing with a conflict, drop the humor entirely. Shift into a neutral, factual gear.
