Well the Exit Polls conducted by news channels and other agencies are a mixture of the survey opinions of people (the number of people may vary from less than 100 to 100,000+), past trends, recent events, etc.....so there is some reality in them. This "some reality" may differ from agency to agency. The main thing is that these exit polls can be almost right on a National Basis but these exit polls can not trace regional dynamics of different parts of India.....I noticed this in last 3 Lok Sabha elections from Bihar to Tamilnadu.
No new channel can predict.. there has to be proper evidence and proof to predict something.. news channels cannot be based on predictions and estimations.. there has to be evidence to prove it..
i think exit polls do work to an extend for predicting situations but not with a strong reliability as they lack any proof. but yes to create a situation like survey and to broadcast the existing situation these polls do matter as these indicate the prevailing situation. however the reliability varies from the organisation or news channel conducting it.
noways..all these polls are manipulative and beyond the actual truth. all these big news channels are interlinked with political parties for their monetary gains. we cannot trust such a conclusive polls from their end. even if they are conducted fairly, they cannot reach each and every person and so these polls cannot be totally be relied upon
Well, they cannot be completely relied upon because not all the people do the voting in a right way and some do not even vote. So the reliability factor of these exit polls still remains questionable. However, these polls do help in getting an idea on the issue. I think media can improve on the functionality of these exit polls so that they can be more reliable.
