Effectuative thinking, unlike causal thinking, is bottom-up. It doesn’t start with a final goal in mind. Instead, as Sarasvathy explains, “it begins with a given set of means and allows goals to emerge contingently over time.”
Sarasvathy identifies four main principles to approaching your work in this manner:
1. Start with what you already know how to do well.
2. Filter your efforts to avoid big downsides not to select for big upsides.
3. Work with other people who bring new abilities to the table.
4. Take advantage of the unexpected.
