From the article:

“Campbell’s love of invention-oriented science has guided his career. “However, as I approach my midcareer stage, I’m also finding that focusing on invention alone can be kind of scary,” he says. Hypothesis-driven research will always lead to an answer, even if it is not the right answer. “In contrast, invention-driven research is often binary,” he says. “It either works or it doesn’t work, and the failures are rarely publishable.”

Campbell says his graduate students offer a steady flow of creativity and imagination and help him sustain this invention-focused model to keep developing FP-based tools.”
