A dictatorship is hardly a plus. A free and plural society where everyone can research what he is most interested, the field that is his passion, with no directions or borders a priori in any direction. That is what is required for maximum success and also why pluralistic, liberal democracy are the most successful. Scientific though is most fruitful and nourished by the maximum freedom possible. "Direction" from the government is not required and rather harmful not helpful.
Reality testifies to this being a fact.
Well this is not entirely true. Let me give an example. NIH, UNDP, TWAS etc allocate a significant portion of grant funding for basic and applied research in tropical diseases such as Cholera, Malaria, Schistosomiasis, Leishmaniasis etc. It is fine if the money is plentiful and someone wants to work on the pathogens responsible for these diseases. But the simple fact is, all these disease can easily be controlled, in fact eradicated by simply investing the in the basic infrastructure. Instead of wasting money on making vaccine and developing therapies (millions of dollars have been poured in Malaria and cholera vaccine with no success in past 100 or so years) for the water-borne diseases, a fraction of that money can be used to provide clean drinking water and improving the sanitation. That will automatically result in the reduction and even eradication of such diseases as it happened in the Europe.
However things are not as simple as they appear. There are people who have made their entire careers while working on these problems. If the money goes for improving the infra-structure than these people will lose their jobs. So freedom is fine but only when there is plenty of money at hand. We have to set out priorities, what should be funded first, what should be funded next and where we need not to invest altogether.
My PhD work was on developing a cholera vaccine. I remember during my defense (viva voce), I was more critical of my work than my examiners. At one point they even asked me that if I was so skeptical about the whole approach, why I wasted my four years? For the following two reason I replied to them:
A. To be able to learn the basic and advanced techniques in Molecular Biology and Immunology.
B. To get the PhD; that is more like getting a driving license. Once you get the license, you are free to drive whatever the car you like.
Indeed my two hours long defense pissed my supervisor off but at the end of the day, I had secured my PhD with A plus. Soon after getting my PhD, I left the cholera field and moved to the virology field which is far more important and relevant in today’s world.
