I have added a link the The Oregonian's searchable ALJ database to the sidebar of this blog. You can find it under "Resources of Note." I shall maintain the link for as long The Oregonian keeps the database available.
Knowing a judge's stats is just one factor. It is also important to know how a particular ALJ approaches a claim and how a particular ALJ conducts a hearing, because they all have different styles.
This is why, in my opinion, it is important to have a local Social Security disability lawyer who knows the judges in your state.
