Why are we not congruent in our analysis or decisions.

I am watching the TV & listening to the opinions of the experts about India winning semi finals in World Cup Cricket. Since India won against Australia, so every one appreciates the team members & the process of their winning with all the possible praise. But when the same team lost in the past I heard the same experts criticising the same players with all possible negativity. It appears we give our opinions after colouring with the success or failures. Why? It appears we do not have faith in our analytical ability at one hand & on the other we don not want to reduce the flavour risen among the audience because of success. During the time of defeat the opinion leaders always try to assess the mood of the audience & give their analysis accordingly. Thus anlaysis  does not remain fair. Why? We do not have courage to fight the emotions of the audience. In the process we loose a golden opportunity to learn. I am a bit perturbed by the praise as it took away the opportunity from players to learn. May we the team does that in closed doors.
