Our take
Based on the ratings of 21,442 students, a sample of their written reviews and the syllabus, as the course stood in February 2025. No course pays to be reviewed.
Gail Miller's course is a two-hour talk on unconscious bias, split into 36 short lectures across nine sections. It explains why the brain takes mental shortcuts, names specific biases, covers what they cost at work, and then spends its longest stretch, about 46 minutes, on ways to counter them. The pitch is aimed at HR staff, recruiters and hiring managers, though the audience list says anyone can take it. More than 56,000 students have enrolled, and there are no prerequisites.
Reviewers mostly like the teaching. They describe Miller as clear, engaging and well paced, and several say the examples were easy to relate to their own lives. One learner came away with new terms like halo and horns bias and affinity bias, plus strategies such as stereotype replacement. Complaints are small. One reviewer found it long and all talking, with no visuals to break it up. Another hit dead resource links, and a third says the exercises need printing. The two 1-star reviews call it too United States focused and condescending.
With 21,442 ratings averaging 4.5, and about 10,200 of them five stars, the course has a solid track record. The material was last updated in February 2025, but the 23-minute Coronavirus lecture at the end feels dated, and one reviewer says so. It is a paid, quick starting point for self-awareness and better workplace habits. If you want hard research or a deeper build-out for a diversity program, look elsewhere.
Pros
- Miller's delivery is called clear, engaging and well paced, with on-screen text that helps note-taking
- Names specific biases, such as halo/horns and affinity, and gives fixes like stereotype replacement
- Short at about two hours, split into 36 brief lectures across nine sections
- Reviewers find it useful in personal life as well as in hiring and workplace decisions
Cons
- Mostly one presenter talking, and one reviewer wanted images or media to keep it easier to absorb
- One reviewer hit dead resource links, and another says the exercises have to be printed rather than done online
- The 23-minute Coronavirus lecture is dated, and two reviewers call the course US-centric or condescending
It's a good course that explains the kinds of bias we can encounter and gives clear examples.
Labeled All Levels with no prerequisites. It suits newcomers to bias training more than seasoned HR or DEI veterans.

Course Description
WARNING: This course is not for everyone. You should only consider this course if you want to expand your mind, reveal and overcome unconscious bias, and improve relationships, productivity, morale and diversity in every area of work and life. If that is you, then keep reading.
Do you ever feel like you judge people too fast?
You see them in the grocery store or during an interview and your mind lights up like fireworks. They’re too fat, too skinny, too tall, too short, too ugly, too pretty, too clean, too inked, too tough, too weak, too stupid, too smart, too rich, too poor, too old, too young.
Everyone has those thoughts.
The problem is they block you from discovering who that person really is. They stop you from asking yourself what they might be like on the inside. So you avoid them. You skip them for jobs. You never ask about their story and you miss out on valuable relationships.
And the bigger problem is you only engage with those who fit your idea of how a person “should” be. So you create a circle of influence around you that lacks diversity, open communication, and growth. All of that holds you back in untold ways in business and life.
You Can’t Change Other People But You CAN Change Yourself
Your instincts never change, and you can’t force others to be different either. But that doesn’t mean you can’t adjust your own habits to lift yourself up to new horizons where you can see the world, and other people from different and more useful perspectives.
With a bit of effort and minor adjustments, you can begin to realize old, ineffective thought patterns and replace them with new, more useful tools and behaviors.
What Are Unconscious Biases?
Unconscious biases are perspectives you hold that form automatically based on a variety of information sources from the world around you.
They’re kind of like what happens when someone throws a ball at your face. Your hands automatically fly up to protect your head. Unconscious biases are a type of automatic, instinctual self-defense mechanism as well.
When you see someone with tattoos and you judge them as “bad” or “trouble,” you might avoid them because your bias told you they’re no good. Sometimes that judgment might be right. But what about when it isn’t?
What if that person is the nicest, friendliest, most loyal and trustworthy human on the planet? What if they hold the key to the biggest opportunity of your life? Too bad. You will never know, because you judged them incorrectly and you did it automatically.
Is This a Corporate Problem Too?
Unconscious bias is a problem for everyone, and when it enters the workplace, it digs a pit of despair for businesses. Human Resources, recruiters, and anyone who hires or works together will likely face the challenges of unconscious bias.
The problem is, it leads to weakness in the business. It’s like building a castle on a foundation of toothpicks. Without accounting for unconscious bias, you end up with a workforce made of people who were judged “good enough” based on shallow social cues, rather than the value they can actually provide.
Ultimately, you create an environment that lacks diversity, innovation, and any kind of creative thought at all. In this course, I’ll show you how and when to say, “So what?” so you can see beyond those biases to find, recruit and grow the best team and company possible!
What Will You Learn in this Course?
In this course, my goal is to help you begin to recognize different kinds of biases in your life. Together, we will review types of biases most people don’t know exist. We will also work to help you overcome those biases in your own life so you gain perspective, insight and the ability to make conscious choices that serve you better.

I really enjoyed this course. It spoke about different types of biases, and I was able to relate some of the examples to my own personal experiences. It helped me become more self-aware and more mindful of how bias can effect the way we see and treat others. I think this course is very important for both personal and professional growth.
By Dawn Clayton on 12/3/2025
I did like the course and the information it conveyed. The only reason it didn't go to 5-stars is because some of the resources went to dead-ends, but that can happen over time. I would suggest a yearly review of the links provided to make sure what you said was available, actually is - and offer alternatives when you find those glitches.

This course was by far one of my favorites in uDemy. Below are several reasons why I gave this a 5-star review. - Instructor had great tone, pitch, enunciation and pace - Course content structure was clear and concise - Sections had on-screen text which helped with note-capturing - Exercises were useful and motivating - Resources were an added bonus! Thank you for an engaging and cohesive course!

Good content. I learned about types of bias that I was unaware of (e.g. halo/horns, affinity) and some new strategies to reduce my own unconscious biases (e.g. so what?, stereotype replacement). One suggestion: I think if the exercises were a digital part of the course rather than having to print them out, that would encourage better participation in them. And some feedback on the video footage: The production is far better than I could do, but I found a couple things distracting. The different camera angles seemed to have different color balance, so as they switched you'd go from really good lighting to washed out to dark. I don't know the first thing about how to fix that, but I think it could be fixed. And it seemed like some of the shots were redone at the end of the shoot day and edited into the middle of the video, which made for noticeable transitions. Some of the sections were very long, so I understand that it's probably impractical to reshoot the entire section if there's a mistake here and there.

This seems very Psych 101 so far. I know about unconscious bias and this seems very remedial.
I'm just not feeling that I'm learning anything new. I am getting many things I've learned before reinforced.
