"Almost all judicial decisions... can be assigned an ideological value."

"Those favoring, say, prosecutors and employers are said to be conservative, while those favoring criminal defendants and people claiming discrimination are said to be liberal."

If you can get past that sticking point, you can code everything into an immense database, produce some amazing-looking charts, and reach conclusions like "Court Under Roberts Is Most Conservative in Decades." You can then see into the future:

If the Roberts court continues on the course suggested by its first five years, it is likely to allow a greater role for religion in public life, to permit more participation by unions and corporations in elections and to elaborate further on the scope of the Second Amendment’s right to bear arms. Abortion rights are likely to be curtailed, as are affirmative action and protections for people accused of crimes.

Affirmative action is likely to be curtailed? But you just said decisions favoring employers are conservative, and decisions in favor of persons claiming discrimination are liberal.

Almost all judicial decisions can be assigned a molecular weight, too, provided you don't object to talking nonsense.
