Unconscious Bias: The Innovation Killer

"Is this room diverse?"

I asked that question in front of a room full of women in San Diego at the Women in Sales Leadership Retreat (hosted by Women in Sales) - and then I answered it before anyone could.

Of course not. I was standing in a room full of women... in sales... at an event... for women... in sales.

Except. That wasn't actually my answer.

But also? Yes. Absolutely yes. Literally everything else about us is diverse.

I wasn't there to talk about diversity metrics. I was there to talk about what kills the value of diversity before it ever gets a chance to work.

What diversity actually means

Here is my direct, no-apology definition: diversity is the presence of meaningful differences in identity, background, perspective, or experience.

Which means everyone in that room - and every room - is already diverse. The question is whether anyone’s acting like it.

Franz Johansson wrote about this in The Medici Effect. His argument: the most innovative ideas happen when diverse backgrounds and disciplines intersect. “All new ideas,” he says, “are a combination of existing ideas.” The broader the collective experience in a room, the better your odds of hitting that winning combination.

I’ve lived this in both directions.

Earlier in my career, I was part of a pricing and packaging initiative led by Sales. We had a real problem: new logo acquisition was struggling, and we believed new packaging would solve it. The idea wasn’t bad. The room was just too narrow.

We never asked Product about constraints.
We never looped in Marketing on positioning.
We never considered what CS would have to manage on the back end - the upgrade paths, the NRR impact, the customer confusion we were about to create.

We thought we were solving a problem. We were actually creating three new ones.

I’m currently in a pricing and packaging exercise at Sendoso. Different experience entirely. The cross-functional perspectives, the competing concerns, the moments where someone says “wait, have you thought about…" That friction is the point. 

That’s the Medici Effect in practice.

But...

Here’s the catch

Hitting your diversity metrics isn't enough. You can fill a room with people who look, think, and sound differently and still get none of the benefit. Why? Most often, it's due to unconscious bias. Ideas get dismissed before they're explored. Voices get interrupted before they finish the sentence.

But let me be clear: I am not talking about the bias people know they have. I'm talking about the stuff running quietly in the background. The mental shortcuts your brain makes before you've even finished a thought. The ones that feel like instinct. Like good judgment. Like a gut response.

Those mental shortcuts are called unconscious bias - the invisible barrier that prevents diverse teams from realizing their actual potential.

And when it goes unaddressed, the cost isn't just cultural; it negatively impacts innovation.

We all have it. (Yes, you. Yes, me.)

I asked my fellow women in sales, “Who in this room has unconscious bias?”

The answer: Everyone.

Unconscious bias is not a character flaw. It’s how human brains conserve energy. Mental shortcuts are how we survived as a species. The problem isn’t having them - it’s not knowing they’re there.

Here are 10 of the most common types of unconscious bias:

1. Affinity Bias: Favoring people who remind you of yourself (“Mirror-tocracy”).
2. Confirmation Bias: Seeking out evidence that confirms what you already believe about someone and ignoring everything else.
3. Attribution Bias: Crediting your own wins to skill and your failures to bad luck and flipping that logic for everyone else.
4. Conformity Bias (Groupthink): Changing your opinion to match the group, even when your gut says otherwise.
5. The Halo Effect: Letting one impressive trait make you assume everything else about a person is equally impressive.
6. The Horns Effect: Letting one negative trait color everything you see about a person afterward.
7. Contrast Effect: Judging the person in front of you based on who came before them, not on their actual merit.
8. Ageism: Assuming what someone can or can’t do based on how old they are.
9. Gender Bias: Unconsciously associating certain roles, skills, or leadership traits with a specific gender.
10. Name Bias: Making judgments based on how someone’s name sounds before they’ve said a single word.

‍

Every single one of these shows up everywhere. But four of them are practically hardwired in sales organizations.

Affinity Bias: The manager who hires the candidate who went to the same school, plays the same sport, grew up in the same city. It feels like a connection. It’s actually a blind spot. 

The Halo Effect: Just because someone crushed their individual quota doesn’t mean they know how to build, coach, or lead a team. These are different skills. We promote people for one and then act surprised when they struggle at the other.

Confirmation Bias: Once you’ve written someone off, you stop seeing evidence that contradicts your read. Six months later, you’re wondering why you waited so long to make a move. You didn’t miss the signs, you stopped looking for them.

Attribution Bias: Your territory was great, and you worked hard. Their territory was great, and they just got lucky. Sound familiar? This one quietly poisons team culture from the inside.

The list goes on. But you get the idea.

The question isn't whether these biases exist in your organization. They do. The question is what you're actually going to do about it.

Training is the answer. Or is it?

Everyone wants training to be the answer. The research suggests it often isn’t.

Mandatory one-time bias training is among the least effective interventions in the literature. Some evidence suggests it can backfire - people feel they’ve checked the box and actually become less vigilant afterward.

A  meta-analysis by psychologist Patrick Forscher and colleagues, covering more than 490 studies and roughly 80,000 people, found that unconscious bias training did not change biased behavior.

So what does work?

• Harvard’s Project Implicit offers free Implicit Association Tests (IAT). You can’t address a bias you don’t know you have. Awareness is the starting point, not the finish line. (Source: projectimplicit.net - verifiable, publicly available)
• The combination of IAT, debrief, and interactive training is highly effective, as cited in the Equality and Human Rights Commission 2018 report.
• One person can’t change a culture; it takes a critical mass. Research on gender bias training at the University of Wisconsin-Madison found that behavior change only took hold when at least 25% of a team participated together and there's good reason to think the same dynamic applies to bias work more broadly. That's when group norms actually start to shift. (Carnes et al., Academic Medicine, 2015)
• Blind hiring + structured interviews help to remove the variables that bias acts on before a human ever enters the picture. Unstructured interviews don't measure skill. They measure vibe. Research consistently shows structured interviews are roughly twice as effective at predicting job performance as gut-feel hiring.

The tools exist. The research is clear. The only thing that's ever been optional is whether to use them.

Bias is human. What you do about it is a choice.

You're not a bad person for having bias. Nobody is. It's how brains work. Pattern recognition running faster than conscious thought. The problem isn't having it. The problem is assuming that knowing about it is enough.

It isn't.

Before your next hiring decision, your next performance review, your next pipeline call where you're deciding who gets the good territory... ask yourself what's actually driving that call. Instinct or evidence?

That's the work. It's not glamorous. It doesn't fit on a slide. But it's the difference between a diverse team that performs and one that just looks good on paper.

At Sendoso, we spend a lot of time thinking about what it means to build real human connections - with prospects, with customers, with the people on the other end of a gift or a piece of direct mail. But real human connection doesn't start with a campaign. It starts with how you treat the people in your own building.
