Is Evidence-Based Design Legitimate Or Just Another For-Profit Buzzword?
Not long ago, I left a positive comment about a Dopamine Decor article at a homes and gardens magazine. Then, I got attacked by some troll saying that Dopamine Decor was just some new way for companies to make money off people.
Usually, I do not get involved with things like this, but I felt a strong urge to explain that a lot of Dopamine Decor and Evidence-based Design art is based on real, authentic, legitimate science and medical studies.
In my book, 100 Days Of Happy Happy Art, Evidence-Based Design, I wrote: “From the 1960s until today, serious researchers with very serious studies…from different countries…from different multidisciplinary fields have converged to create a new field called Evidence-based Design.”
Even the National Library of Medicine at NIH, the National Institutes of Health, has a definition of it. “Evidence-based design is scientific analysis methodology that emphasizes the use of data acquired in order to influence the design process in hospitals. It measures the physical and psychological effects of the built environment on its users.”
In cancer center lobby.
Today, Evidence-based Design isn’t just for hospitals. It’s for all of us. It is for many of the places humans go.
What is my role in all of this? A very small one—but I think an important one. Today, my art hangs in hospitals, businesses, organizations, and homes. Using my talent and evidence-based design training and certification, I very deliberately and very strategically create HAPPY HAPPY HAPPY art for built environments.
Here’s one of my paintings as it hangs in the lobby of a cancer wing in one of the U.S. hospitals.
The person in charge of art placement at the hospital apologized for its location on a side wall in the lobby.
She thought I might be offended by not having it centered over the main mantlepiece in the waiting area. I wasn’t offended at all. In fact, people come face-to-face with it as they enter the blood draw area. Putting all artist ego aside—and focusing on patient/people needs—I thought it was perfectly located.
Too Beautiful For Words, 36”x36”
Too Beautiful For Words is a super cheerful “distraction” piece. Getting cancer and getting treated for it is often horrific, and at times, it can make patients and others feel as if they are about to lose their minds or are living through some “other world” reality. I thought adding an upbeat quirkiness to the art would help—in a positive way—identify with the circumstances and would also help release some dopamine (happiness brain chemicals).
Patients, their families, and the staff kept telling me—all the time—how happy this painting made them feel, so I decided to donate two other paintings that evolved over the years into a new evidence-based design series called Symphonies of Love.
Both paintings below are placed today in cancer patient examination rooms. People in this community with cancer or with a loved one with cancer continue to tell me how much they appreciate the heart shape, which simply but beautifully communicates to patients that they are loved.
One of these 61” x 78” evidence-based design heart paintings recently got featured on one of the world’s most prominent online art gallery websites. I was listed as one of sixty-one American artists to follow.

Different Types Of Evidence-Based Design
There’s Evidence-based Design, and then there’s NOT Evidence-based Design.
Here are a few evidence-based design art guidelines. Many of these guidelines come from “A Guide to Evidence-based Art” from The Center For Health Design, research by Ulrich and Gilpin, a case study on best practices in evidence-based design by the Mays Clinic at the MD Anderson Cancer Center, and so much more.
Landscapes
They can be regional, generic, or seasonal. They should have visual depth or open foreground. Trees should have a broad canopy. Savannah and park-like landscapes are preferred by many. Vegetation should be lush. Empty park benches and sunsets should be avoided. The empty park bench might remind someone of loss and loneliness. A sunset might represent the end of life.
Florals
Florals should include familiar shapes of plants and flowers. They should appear healthy and fresh, and flower colors should be vibrant. Gardens and bouquet styles are acceptable. Flowers in vases should be used sparingly and only for variety.
Taking scientific or medical study results and turning them into artistic creations is not the easiest thing to do. There are no step-by-step guides to follow, and the rules need to be there, but sometimes they need a little bending.
The painting above, Healing Flowers, spent time on exhibit in a museum and then in a gallery. It recently sold, in 2025, to an art collector in Fort Worth, Texas. Also, in Jan/Feb 2025, it was featured on the cover of Healthcare Design Magazine. In addition, in 2024, I was also asked to show it in another issue of Healthcare Design Magazine issue. On one international art gallery website, this painting received thousands of views.
While creating it, I tried to adhere to the evidence-based landscape design guidelines for healthy outcomes. By following the rules, I figured I could trigger the brain to create dopamine, which would produce in its viewers feelings of happiness.
If you look closely, you can see through the stems, which gives viewers visual depth. According to the research, seeing through the stems helps humans feel safe. It takes us back to our days of hunting on the Savannah, where dangerous animals could hide in thick grass and then attack us. While the stems were thin, I ensured the flowers appeared lush and abundant. Again, this would suggest an abundance of food.

Using the same evidence-based design guidelines, Healing Abundance also sold in early 2025. It was sold from a gallery in Paris, France, and shipped to a company in Hong Kong with television channels in Hong Kong, mainland China, Macau, and other Chinese-speaking areas. The soil and stems are there, but I wanted to add lush vegetation through the flowers.
Years ago, when I was living in Asia, a good friend who was also a medical doctor ended up in the hospital. I went to visit her with a bouquet of cut flowers in hand. After she got out of the hospital, she told me that a bouquet of flowers was not the best gift. A potted plant would have been more appropriate. When I asked why, she explained that cut flowers will soon die, while a plant in soil continues to live on.
Most everything I do in the creation of an evidence-based design painting is for the health and happiness of viewers.
What Is The Definition Of Evidence-Based Design?
There are broad and specific definitions of evidence-based design.
Here is the definition from the National Library of Medicine:
“Evidence-based design is scientific analysis methodology that emphasizes the use of data acquired in order to influence the design process in hospitals. It measures the physical and psychological effects of the built environment on its users.” (National Library of Medicine, National Institutes of Health)
Even Wikipedia now has a definition:
“Evidence-based design (EBD) is the process of constructing a building or physical environment based on scientific research to achieve the best possible outcomes.” (Wikipedia)
The definition I like best is from The Center For Health Design.
“…the process of basing decisions about the built environment on credible research to achieve the best possible outcomes.” (www.healthdesign.org/edac)
The built environment (people-built surroundings where human activity occurs) includes art, and since my EDAC (evidence-based design) training and certification, I have sold hundreds of paintings based on these definitions.
Some of my first Great Lakes/Lakeside Lovelies paintings using Evidence-Based Design training.
Based on medical and scientific studies, hospital/medical facility patients highly regard familiar nature scenes.
When I first started creating art using evidence-based design, my first creations were what I called Lakeside Lovelies and Great Lakes Lovelies (above). They were familiar nature scenes, mainly along Highway 23 in Northern Michigan. Half of my inspiration came from Lake Huron and the Straits of Mackinac. The air in this area is clear and clean, so my eyes can almost always catch super-crisp images.
The other half of my inspiration came from the abundance and variety of flowers around town, the Upper Penisula and Northern counties, and within my own art studio’s yard. Who would have thought it? Here is a bush—and of all places—next to my garage that inspired many of my paintings. In this area, this bush is a plentiful sight in the Spring, which also makes its stems a familiar nature scene.
Credible research told me that local natural landscapes helped to achieve the best possible health outcomes, and I strongly dislike painting realism (which isn’t a requirement in evidence-based design), so I happily went with a floral contemporary Impressionism style. (Thank you, Monsieur Monet.)
At the beginning of my journey as an evidence-based design artist and having a studio in Northern Michigan (where a few people still have trophy deer heads and bear skins on their living room walls), I decided to have a little fun and help promote art in the area with the new evidence-based design paintings and videos. Here’s an older video. Enjoy!
Is Evidence-Based Design Totally New?
Is Evidence-Design Totally New?
If you asked the 6th BCE Greeks of Epidaurus, they might take you to one of the most celebrated healing centers of the classical world—the Asclepieion hospital. In their hospital, patient rooms faced eastward. Why? It is believed the rooms were intuitively designed and placed toward the sun to promote healing.
Many centuries later, many movements from different countries came together in the 1970s to create a new field called evidence-based design.
Who are the people whose forces created this new discipline? Doctors, Scientists, Architects, Interior Designers, Psychologists, Sociologists, Anthropologists, and many others.

This artist’s journey into Evidence-Based Design
Photo from the back of McLaren Northern Hospital, Petoskey, Michigan
I am known by many titles in the art world: Artist Of Happiness; a modernizer of traditional woodland compositions; a Great Lakes artist; a 21st-century experimental artist; creator of the evidence-based design collection, Symphonies Of Love; creator of the Smart City Art Collection; and more.
At the beginning of my evidence-based design artistic journey, I chose to create a painting depicting a view from a hospital room. The background of The Healing Window features Little Traverse Bay, as seen from the back parking lot of McLaren Northern Hospital in Petoskey, Michigan.
While composing this painting, I imagined myself in one of the patient rooms at McLaren Northern, looking out the window.
I also imagined myself in a patient room or in a healthcare lobby or a waiting area.




Artists always have lots of choices to make. Early in my evidence-based design floral art career, I chose creating happiness (triggering dopamine) over painting realism. My reason? I figured I would have more power to create happiness if I had more artistic power of the flowers. Not only did realism limit my ability to create happiness (dopamine), but according to medical and scientific research, traditional still-life wasn’t an art category most favored within evidence-based design.
So, is evidence-based design totally new? Yes and no. The flowers in this artwork are modern, cheerful, uplifting, and based on current evidence-based design best practices. However, I also wanted to pay homage to the accomplishments of those who came before us by incorporating elements that, especially in the design texture of the vases, evoke a rough, ancient Greek Asclepieion aesthetic.
