There are only two kinds of people
who fail:
those who listen to nobody...
and those who listen to everybody
- Bershere's Formula for Failure

Before undergoing a serious medical procedure, many people get a second opinion from another doctor. If there is a conflict between the two opinions, then perhaps a third opinion should be brought in.

This is in keeping with the 13 principles in Judaism עד שיבוא השלישי ויכריע ביניהם: Ad sheyavo hashlishi veyachriya benehem.

Of course, we can carry this concept further. If two opinions are good, then three opinions should be still better, even if there is no conflict between the first two. And if three opinions are good then why not four or five or six? Perhaps there is no limit to the number of good opinions – the more the merrier.

However, for a typical person it may be difficult to absorb and digest all of this information. After all, each opinion will be different from the others, and the person receiving this overload of information will tend to be confused.

A similar situation occurs when people go on dates, or visit a computer consultant, or when they discuss potential Aliyah plans. Let's look at those cases.

Computer consultants are often asked many questions, and the clients are often confused as a result. Worse, they may have received reasonable responses, but then they approached a consultant for one additional opinion. They then have a difficult position trying to determine what is right or wrong.

Their solution may simply be to make an arbitrary decision. However, that means that they gained no benefit by discussing their issue with the consultant. They could have made an arbitrary decision for free!

It is important to have a single person who can resolve issues for a person rather than having too many people being involved (link this to the other relevant article). Situations arise in which it is proper if there is a single consultant or a single confidant in the case of http://www.oocities.org/GrossmanParenting/Dating/Intro.html">dating, in which case all of the information is brought to the person to a single person the confidante who can be the bottom line answer.

This is also related to questions about whether to move to Israel. People who ask too many people are confused. When they arrive they are also too confused and again they need a single Israeli consultant from the decision about the issues about whether to do Israel until the issues related to how to deal with the inevitable problems that arise once they have arrived in their new country.
