Does indigenous knowledge have a place in mathematics?

the fact that discipline D uses mathematics does not mean that the analyses carried out in D is mathematics indigenous approaches to meteorology etc might yield insights not because they do maths differently but because they draw on different insights. The challenge is whether those insights can be shown to be reliable, repeatable and transferrable to others. As far as mathematics itself goes the test will be does it generate new insight. You'll recall Ramanujan's results were closely linked not least by him to his cultural background, and it took years of working with Hardy et.al before they could be made rigorous and published. Today they count amongst the pinnacles of achievements in pure mathematics.

What's not to like about spreading the net wider and looking at other ways of doing things? The drawback is if you tag it as 'decolonising' or start talking about indiginous people you make it unattractive, not done for its own worth but to utter platitudes in stained glass attitudes about the discipline in question. Talk about insights, innovative approaches, and people will come running, whoever's ideas you are bringing in.
