The problem is that measurable success is going to change the experiment.
If you consider that there is no constant landscape, it's always changing and always an unknown, the best option is to try a plethora of different ideas, hoping some will succeed.
It's more like fighting a war in an unknown battlefield. If you play it just one way, you are more likely to lose than if you try many different strategies at once.
The ones that succeed will be self-sustaining, for as long as they are successful, anyway, and gain you enough ground to compensate for the strategies that didn't work.
If this wasn't true, nature would only have produced one single organism rather than a billion or more.
