Ice fishing is a longstanding tradition in Nordic countries, with competitions proving especially popular. Those competitions can also tell scientists something about how social cues influence how we make foraging decisions, according to a new paper published in the journal Science. And even when studying social foraging decisions, it’s typically done using computational modeling and/or in the laboratory. organized 10 three-hour ice-fishing competitions on 10 lakes in eastern Finland for their study, with 74 experienced ice fishers participating. All told, they recorded over 16,000 individual decisions specifically about location choice and when to change locations.
