to only 5% in the United States. By 1989, Soviet scientists were among the world's best-trained specialists in several areas, such as Energy physics, selected areas of medicine, mathematics, welding and military technologies. Due to rigid state planning and bureaucracy, the Soviets remained far behind technologically in chemistry, biology, and computers when compared to the First World. The Soviet government opposed and persecuted geneticists in favour of Lysenkoism, a pseudoscience rejected by the scientific community in the Soviet Union and abroad but supported by Stalin's inner circles. Implemented in the USSR and China, it resulted in reduced crop yields and is widely believed to have contributed to the Great Chinese Famine. Under the Reagan administration, Project Socrates determined that the Soviet Union addressed the acquisition of science and technology in a manner that was radically different from what the US was using. In the case of the US, economic prioritization was being used for indigenous research and development as the means to acquire science and technology in both the private and public sectors. In contrast, the USSR was offensively and defensively maneuvering in the acquisition and use of the worldwide technology, to increase the competitive advantage that they acquired from the technology while preventing the US from acquiring a competitive advantage. However, technology-based planning was executed in a centralized, government-centric manner that greatly hindered its flexibility. This was exploited by the US to undermine the strength of the Soviet Union and thus foster its reform. Transport Transport was a vital component of the country's economy. The economic centralization of the late 1920s and 1930s led to the development of infrastructure on a massive scale, most notably the establishment of Aeroflot, an aviation enterprise. The country had a wide variety of modes of transport by land, water and air. However, due to inadequate maintenance, much of the road, water and Soviet civil aviation transport were outdated and technologically backward compared to the First World. Soviet rail transport was the largest and most intensively used in the world; it was also better developed than most of its Western counterparts. By the late 1970s and early 1980s, Soviet economists were calling for the construction of more roads to alleviate some of the burdens from the railways and to improve the Soviet government budget. The street network and automotive industry remained underdeveloped, and dirt roads were common outside major cities. Soviet maintenance projects proved
