Vet (v.)

     Originally, a horse-racing term, referring to the requirement that a horse be checked for health and soundness by a veterinarian before being allowed to race.  Vital signs, general health, physical condition, and signs of illness are checked along with the horse's demeanor, alertness, and interactive behavior.  Eyes are checked, plus a hands-on exam is done for any problems with muscles, tendons, joints, and bones.  The horse's stance and movement at various speeds are observed.  The horse is vetted to assure it can safely complete the race.
     Now, the word vet has been extended to people who need to be checked out before being employed, becoming a political candidate, or rated as an expert.  Physical and mental health needs to be analyzed.  People are vetted for their qualifications, honesty, integrity, personal conduct, and past history.  These background checks may reveal strengths and weaknesses, affiliations, and vulnerability to pressure, extortion, and corruption.  People need to be vetted to assure they are the best candidates for their race.
     Professional papers and reports are vetted before being published or aired.  Most of us trust that what we hear and read has passed some sort of previous, trustworthy examination.  At times, we have to do our own research and judge for ourselves.  We need to detect signs of  bias and manipulation.
     Whether we are checking out the ponies, the politicians, or the pundits, we need to assume some responsibility for vetting before believing all is well.
