Is Collective Wisdom always Correct?
At the starting point of human evolution timeline, the progress was very slow and full of dangers. Learning was at the cost of many human lives. In the beginning, man was a hunter and did not have a stable life. He was always on the move because animals which he hunted were also capable of running. Life of hunting was not easy.
They were on lookout for more stable life. To be able to stay put at one place. For this, humans had to enable themselves replace their diet with grains and cereals which could be grown near their abodes. As we know there must had been plenty of vegetation all around. But today we know that all of it is not suitable for animal consumption. Plants have been here from the beginning and since they could not move from one place to another to defend themselves, their defense mechanism was already in place for survival. As a result only a few of the plants are useful.
Humans did not know what was good for eating and what was not good. It was all a hit and trial process with some of them scarifying their lives. But with the passage of time, information begun to build up and thus the present generation was better equipped than the previous one. Now we have reached a stage where a huge treasure of knowledge is at our disposal.
So have we become so wise and knowledgeable that we cannot commit mistakes? The answer is sadly no. we are committing mistakes. One reason is that we work in groups with members having all shades of knowledge. Thus the resultant knowledge is averaging out.
Take for example the green revolution in the North India particularly Punjab. It saved the masses of the country from starvation. There was a great scarcity of the food grains. India was dependent on the mercy of the countries like USA and USSR. Green Revolution introduced the modified varieties of wheat and rice which have high yields. The state increased the production so much that it was able to feed all the country with food grains.
But the real results of that exercise are now becoming evident. The land was drained of all the nutrients. It was not kept any time fallow to regain the natural strength. The result was the increased use of fertilizers and insecticides. The water footprint was very high for the production of these crops. Since the river water was not sufficient, the underground was exploited up indiscriminately. Since the quality control during manufacturing was poor, many heavy metals which are very toxic slowly made their way to underground drinking water. The water table went deeper. The disastrous effects are now visible in the form of many fatal diseases affecting the children in the Punjab.
On the other hand, there were negative effects elsewhere which disturbed the equilibrium. The states like Kerala, Tamil Nadu and West Bengal which were naturally suited for rice production stopped or tried to change the crop patterns with negative results. So it seems that for short term Green Revolution was a blessing but in the long run it was a collective failure.
