Elective Agriculture

Sometimes you keep planting the same stuff in the same place. It wears out the soil by consuming the same nutrients until the rate of replenishment falls below the rate of extraction. Then the crops start coming out 'weeny, weedy and weaky', as that great Roman once said.

This is the same kind of phenomenon as can be observed when an institution begins to feed on itself. If the same structures and powers have been in place too long, the amount of profitable divergence begins to drop. Like the crops, the gene pool is too small for adaptation; the same resource burdens begin to consume ever-decreasing resources, and the crop starts coming out tainted with mediocrity.

It then becomes time to practice elective agriculture. This is like elective surgery but applied to plants. You need to prune plants that can survive it; remove or rotate crops that are leaching out the last resources, so that the soil can recover; and if you are desperate, cut down and burn some plants to return the resources to the soil.

I've always believed that self-selecting cabals (such as the College of Cardinals, many political parties with a cadre system, some administrative teams in some corporate entities) can be very focussed and powerful. However, if the talent pool begins to thin out, this essentially propagative strategy can become self-defeating. That's because limiting your choice to a small pool in a social context normally results in a fall in memetic diversity. The same people say the same things, and 'thinking outside the box' becomes 'thinking more fantastically within the same box under the illusion that it is becoming larger'.

The result is that you begin with powerful leaders who are replaced by shadows of themselves who are then replaced by shadows of shadows. If the powerful leaders outlive (or purge, or otherwise eliminate) their shadows, they will be replaced by the shadows of shadows. A simple and crude mathematical analogy is to consider a 'shadow' as the 40% version of its original. Then the 'shadow of a shadow' is a 16% version of the original. It will take about six of these to replace the original, and that will still only be 96%, assuming that these shadows are additive and do not overlap.

This is why elective agriculture must be practiced. Crop rotation and the selection of new strains must be de rigeur for any organisation seeking to retain its growth potential. At the same time, that selection process is difficult. You can't be choosing new strains for the sake of having something new; you might plant weeds instead. Or the shadows of the shadows of crops.

From crops to outcrops – that is what will happen when wrong-headed replacement policies (either poor or no replacement) are followed. It's always a good thing for the farmers to have a look now and then at their livelihood, before it's all gone.
