Much innovation happens when people combine knowledge from different disciplines. But some people are more likely to reach outside of their areas of interest and expertise than others. Researchers investigated why by studying people’s “mindsets” about interest and their impact. They found people vary — some people lean more toward the view that interests are inherent in a person, simply waiting to be awakened or found (a fixed mindset of interest). Others lean more toward the view that interests can be developed and that, with commitment and investment, they can grow over time (a growth mindset of interest). They reasoned that these mindsets might affect how open people are to new or different interests, whether they be in arts, science, business, athletics, or other areas. In studies, they found that students with a stronger growth mindset reported being more open to areas outside of their interests than those with a stronger fixed mindset. Their research also suggests that a growth mindset may promote resilience in maintaining interest when a subject becomes challenging and that a growth mindset may be cultivated.
