SCOTUSblog has a report on the oral argument in Biestek v. Berryhill, the Supreme Court case on "whether the Social Security Administration may ground a decision to deny
benefits on the opinion of a vocational expert who refuses to disclose
the data on which that opinion relies." The bottom line:
... Both of the lawyers and several justices danced around a central underlying problem: Many people suspect that vocational experts’ opinions, whether favorable or unfavorable to claimants, have tenuous support. Indeed, vocational experts increasingly have become black boxes, churning out de facto decisions in many disability cases based on little more than guesswork. ...
The justices certainly identified several possible bases for a minimalist decision. They also, however, raised tantalizing hints of a broader ruling. If the court were to embrace the narrow view of the “substantial evidence” test, administrative agencies would have sweeping license to engage with arguments against their preferred decisions. On the other hand, several justices seemed disposed to force the Social Security Administration finally to address long-standing objections to the arbitrariness of vocational experts’ opinions.
I think there's reason to worry that Social Security will not be ready for the Court's decision. It's not a mere suspicion, it's a fact, that, at best, vocational expert testimony is little more than guesswork. Mostly, though, it's based upon the Dictionary of Occupational Titles (DOT) which is almost 40 years old! Nobody, including Social Security, thinks the DOT is reliable in 2018.
