We know in the physical ecosystem that biodiversity is healthy and important. People can buy into that. We know that biodiversity fosters resistance to pathogens and invasive species. When you explain to someone that the human mind may not be so different, that it's important to have a diverse array of emotions—joy, sadness, love, admiration, guilt—and that these are all important pieces of our internal human emotional ecosystem, people can understand that. People appreciate that diversity is important, that maybe it's some sort of spice of mental life.
When you frame it that way, people are more readily able to not put such a premium on positive emotions and, in some situations, try to foster other kinds of experiences if they think it's part of a more diverse psychological life and repertoire. Framing it less as pushing positive emotions down, but as letting all emotions grow and thrive. They're all important sources of information for us and we have them for a reason. We have evolutionary goals; people can understand that. That's one way we've been thinking about trying to frame this. You don't just want to grow one kind of plant in your garden, you want to have a diverse array.
