Most trial lawyers know a few “rules” to live by… i.e. Irving Younger’s 10 Commandments of Cross Examination.
One of the more common rules you hear is to “steal your opponent’s thunder.” As a plaintiff’s attorney, when you give your opening, you want to get all of the important information out… good or bad. This is supposed to weaken the blow of the defense attorney, who no longer gets the impact out of the bad information that he once would have.
The Deliberations blog has a link to some social science behind this. It’s conclusion is simple: if someone only hears the good, they think they’re not getting the entire story.
It’s all about credibility. If you don’t have credibility with the jury, your client, other attorneys, etc, you won’t get far.
