Imagine a late Tuesday afternoon in a downtown Chicago conference room. There’s a certain corporate flatness to the overhead lights. Instead of filling out workbooks or watching a grainy video of actors navigating fictitious office conflicts, a group of mid-level managers are seated around a table. Rather, they have little laminated cards in their hands. rearranging them. reading them out loud. debating the true meaning of a card from time to time. The facilitator is grinning. It seems like something is working.
This year, corporate diversity training programs have subtly incorporated theory trading cards, which are tangible, collectible-style cards printed with psychological and sociological frameworks. Given how much of the DEI discourse in 2026 has been influenced by digital tools, AI-assisted feedback platforms, and virtual reality scenarios, this is an unexpected development. Here are the cards, though. tangible. Easy. useful in ways that are still being discovered.
Once you see it, the appeal seems to be based on something fairly obvious. For decades, diversity training has relied on passive formats, such as workbooks, videos, and presentations, in which participants absorb information rather than actively engage with it. According to Harvard Kennedy School research, legal compliance-focused training frequently causes resistance rather than introspection, with staff members viewing it as something to survive rather than absorb. Theory trading cards appear to completely avoid that. With a card in your hand that asks you to defend or refute a particular notion about identity, power, or organizational behavior, you can’t really be passive.
A single idea, such as self-determination theory, stereotype threat, in-group favoritism, or institutional framing, is usually presented on each card in simple terms with a brief real-world scenario on the back. Participants are required to draw cards during a session and relate the ideas on them to real-world workplace observations. It sounds almost too simple. Additionally, it seems like something that ought to have been attempted thirty years ago.
The format seems to work in part because it feels more like a conversation people are having for themselves than a lesson. The results of Frank Dobbin’s extensive research on the efficacy of diversity programs consistently showed that mandatory, compliance-driven formats performed worse than voluntary, culturally framed training. Even though a card game is technically required, it doesn’t feel that way. That may be a minor psychological trick, but it could have a big impact.
Slideshows just don’t create the productive friction that is introduced by the trading mechanism, which allows participants to swap cards, argue for a better fit, or contest another person’s interpretation. Instead of being a hindrance to the exercise, disagreement becomes a part of it. That’s not a minor issue in a room where people frequently arrive guarded and depart unconvinced.
It’s honestly unclear if this results in long-lasting behavioral change. Diversity training has a long and somewhat humble history of creating positive emotions in the room that fade by Monday. According to the Dobbin research, even the most well-thought-out training fades in the absence of organizational scaffolding, such as a genuine business commitment, leadership modeling, and accountability structures. A biased promotion process cannot be resolved by a theory trading card alone.
However, there is something noteworthy about this specific format’s spread across HR departments from Seattle to Frankfurt. Someone chose to give them something tangible, allow them to disagree, and observe what happened after decades of trying to influence people’s thoughts by dictating what they should think. That might have always been part of what was lacking.
