Heather Doggett is the Founder and CEO of Immerse Universe, Masterful Impact Consulting, and Scream Score. A zoologist-turned-operator and experience designer, Heather spent decades in zoos and aquariums spanning animal care, interpretation, education, training, operations, and exhibit design—often blending mission-driven content with theatrical techniques through seasonal events and a troupe she founded, Theater Gone Wild. Today, she helps organizations design for impact using human-centered and co-design methods, while also leading Scream Score, a biometric app that measures emotions during live experiences. In this interview, Heather talks about the power of theater, co-designing experiences with the staff, and measuring fear.

“I just knew the power of theater.”

Heather explains that awe, magic, and surprise trigger a psychological state where people become more receptive to new perspectives and behaviors. She describes how moments of spectacle—“beauty and spectacle and magic and sparkles and silly and fun”—create optimism and connection, opening the door for cause-based action far more effectively than signage or information alone. Entertainment becomes the “magic sauce” when mission-driven institutions intentionally create those moments and then support guests with clear, hopeful paths to act on what they already care about.

She cautions that “pizazz and spectacle” without the follow-through falls flat. The effectiveness comes from designing the awe and pairing it with the next step—tools, prompts, and choices that make desired actions easy and meaningful. That balance reflects Heather’s science-meets-theater mindset: understand the psychology, engineer the moment, and design the bridge from emotion to impact.

“Co-designing is a scary word, but I'm telling you, it is the can opener to the special sauce.”

Heather argues that operators should bring employees into the design process—not just solicit ideas on sticky notes, but practice true human-centered design that uncovers barriers, motivations, and benefits for team behaviors. Rather than prescribing one-size-fits-all scripts, she suggests asking, “What would be meaningful to you?” and shaping guidelines that let people act authentically. When staff co-create recovery tools, onboarding, and daily workflows, ownership rises and behaviors stick because they are easy, popular, and fun—not just mandatory.

She also emphasizes behavioral economics: people will default to the “easy” benefit of clocking in and out unless new benefits outweigh the status quo. Leaders must lower barriers (tools, time, permissions) and raise benefits (recognition, autonomy, social proof). Even unglamorous topics—like ladder safety—can be gamified and made culturally “popular.” The goal is an immersive employee experience where back-of-house spaces, processes, and rituals reinforce the same magic promised on stage.

“Now Screamscore is out on the market, and people can compete with their friends to see who is the most scared on a roller coaster, escape room, or haunted house.”

Scream Score translates real biometric signals into playful competition and operational insight. Heather explains that simply measuring heart rate isn’t enough; the platform leverages wearables and an individual’s historical data to normalize differences and detect the true stress (fight-or-flight) response. That yields more accurate “fear” scoring for guests while opening a window into other emotions—what she calls “experience score”—that museums and attractions can use to evaluate and tune shows and exhibits.

Looking ahead, Heather is exploring show-control integration so environments can respond dynamically to a group’s collective state: ramp down intensity if scores spike too high, or trigger a payoff when hype reaches a threshold. She also notes accessibility: the app is free, operators can provide loaner wearables, and they’re researching dedicated devices. The bigger vision is designing experiences for change—using emotion metrics to prototype, iterate, and measure impact with the same rigor as attendance or revenue, but with far more relevance to guest outcomes.
