Buki’s presentation and personal examples really brought the talk together, and I thoroughly enjoyed it.”

“I Don’t understand! That was our talk last night at the latest Fellows event with Buki Mosaku helping us to understand how to just clarify the situation. His book “I Don’t Understand” helps individuals and businesses bring clarity to [navigating workplace bias]our discussions and actions. So pleased I attended. Buki reminded me that it is good, no matter how hard it can be, just to seek to understand. Generously hosted by Stephen Day FCIPS and Kantar and arranged by Daniel Abda.”
“It was an incredibly insightful session, which all should take notes from. Discussing sensitive topics that corporate companies usually don’t like to talk about was needed to break the barrier of formality. I would recommend all to join the session.”
“I have just listened to Buki’s summary covering directional bias, reverse bias and defensive fragility and it’s powerful stuff. Worth a listen and consideration, as the industry looks to embrace D&I.”
“It’s fascinating what you do… I’ve learnt a bit more… You’ve done a fine job, so I’m grateful”
“Wow Buki you really do talk so much sense, I could listen to you all day. We need to have a better understanding of reverse bias and work together. You should be a mandatory part of any firm’s training program”
“Buki is a fantastic speaker, he keeps everyone engaged and delivers with such energy. His passion shines through and I have been able to use what I have learnt on this course with many other topics too.”
“This was an excellent training session. I feel strongly that it should be rolled out to all Aon colleagues as a compulsory session to help develop an inclusive culture where all colleagues are respected and better understand their interactions. This will also help with working with our clients.”
“It was an incredibly insightful session, which all should take notes from. Discussing sensitive topics that corporate companies usually don’t like to talk about was needed to break the barrier of formality. I would recommend all to join the session.”
“It was fantastic. I thought the way of reframing and rethinking how to deal with gender bias was impactful. Your statement of us continuing to do the same thing over and over expecting different results resonated with me. And the tangible skills provided for calling out bias in a manner of enquiry was very valuable.”
“I have never seen such enthusiasm shown on a webinar before. Buki should be Prime Minister !!”
“Buki Mosaku thank you for an interactive and engaging session and for giving Sky colleagues some tips on how to navigate bias in the workplace (race and gender), loved your energy”
