Claimants Denied Disability Benefits Don't Go Back To Work; They Just Keep Trying To Get On Disabiltiy Benefits

     From the Social Security Bulletin, the agency's scholarly publication:

This article examines the experiences of Social Security Disability Insurance (DI) applicants aged 51 or older who were initially denied benefits because the disability examiner determined that they could perform either their past work or other work. ... We find that few older DI applicants who were denied benefits on this basis resumed work at a substantial level following denial. More commonly, applicants denied at this stage continued to pursue benefits, often successfully. Nearly two-thirds of initial work capacity-related denials were ultimately allowed DI benefits after appealing the initial decision or reapplying, and our estimates suggest that many of the rest claimed Old-Age and Survivors Insurance benefits before they reached full retirement age.

     Is it just me or does this suggest that it would be fairer to allow more of the disability claims filed by older people? Denying so many of the disability claims filed by older people creates misery and doesn't end up saving much money anyway. It makes work for me and other attorneys but that's certainly not a valid policy objective.
     Also, do you see evidence in this study to support increasing the age categories in the grid regulations? Should 55 or 57 be the new 50? Where is the proof that making this change would be a reasonable thing to do?
