The early part of the Vedic period, was an age of economic self-sufficiency and consequently there was little scope for an exchange of commodities. All the rural centres were self-supporting. Every house-holder produced the necessaries of life—his farm producing his food-grains and other necessaries, the industry of the women of his household supplied him with his clothing, while the craftsmen attached to the village did the rest. Consequently, there was no inter-dependence between two neighbouring local areas. The surplus product was kept for future consumption. This state of full economic independence did not however last long. Society became complex.
A large section of the community gave up the simple agricultural life; the primitive arts and crafts drew away a large number; owing to these and various other causes, there arose a scope for interchange of commodities between different local areas.
Answer:
Confirmation Bias
Explanation:
Confirmation bias is a phenomenon wherein decision makers have been shown to actively seek out and assign more weight to evidence that confirms their hypothesis, and ignore or underweigh evidence that could disconfirm their hypothesis. As such, it can be thought of as a form of selection bias in collecting evidence. Confirmation bias is important because it may lead people to hold strongly to false beliefs or to give more weight to information that supports their beliefs than is warranted by the evidence.
