This is wrong too. A great book called Thinking Basketball talks about this. Most fans remember comebacks, so in their mind, it happens more often than you think. The better NBA teams usually have the best first-quarter point differential. Especially in regular season games. I found a link where he talks about it. And BTW, this is also true for football.
"To answer the question the way it is phrased here, NO, points count the same throughout the game. 2 points in the first quarter are the same as 2 points in the fourth quarter.
If you are wondering in what quarter points increase the odds of winning the MOST, scoring more points earlier is better. Similarly, the best teams in the NBA have stronger point differentials EARLIER in the game (eg 1st quarter). The 4th quarter is really the only potentially meaningless time in NBA basketball.
I'd cite the number of studies on this, but my blog is down. However, they can be found in my upcoming book, which covers this issue in some detail." -
