Birds of a feather stick together. And that works. Ideas spread quickly within the group and communication feels easier, since everyone is on the same page.
Until the ideas run out. Or ineffective, unhelpful behavioural habits are socially reinforced.
Closed systems are just that, closed. No new information. No new ideas.
Play football all year round in tournaments, leagues, and festivals and the chances are you are in a closed system. The name of the competition changes but not much else. Same faces, same decisions, same game.
And that’s the challenge for sport. Diversity. New ideas worth spreading.
Kids want to play football. For the same reasons birds of a feather stick together.
Kids need to pick up a wide range of movement skills. For the same reasons, new skills promote a diversity of options.
Sport mirrors life.
Talk a good game. Or learn how to play a good game. The choice is yours.
