Being effective is important. Effective means it works – it does what it is designed to do.
Seatbelts are effective. They reduce casualties on the roads.
Social media is effective. It’s designed to keep our attention as long as possible, in order to sell that attention to advertisers.
Just being ‘effective’ isn’t enough. We also need to be good – to do the right thing [at the right time].
Some other examples:
Tesla Model Y.
UN Sustainable Development Goals.
‘The Wealth of Nations’.
The thing you are building probably isn’t quite as complex as ‘democracy’ … Even so, it’s worth asking:
Is this effective?
And is it good?
