I've seen that. There's definitely some good truths in it.
  But...
  ..there's a flaw right in the title.
  This is in the lab.

  *IF* we could change the environments they go back to AFTER they
  leave the lab, then _yes_ it's -possible- to fix it.

  But... I've seen people who turn to the thing that made them
  happiest over and over and over again (usually it's what's
  considered the harder-to-get-off-of family, which are the
  opiates) - because, well, their lives suck, as far as they're
  concerned.

  There's _some_ truth when they say, "It's not them, it's the
  drugs talking" - that's a good social lubricant to help people
  not be excessively harsh on people who keeping returning to
  their happy spot over and over again... especially when all they
  present is criticism and blame rather than cash or other types
  of happiness. But "it's the drugs talking" isn't 100% true -
  it's only as true as "it's the alcohol talking"... in short,
  loose lips. Wake me up from a dead sleep and I'd do the same
  thing as any drug does.

  Sometimes people who leave military or prison or school (not
  much difference) can't cope. They're thrust out in "da world"
  after being constrained by their environments and they KNEW that
  environment but they don't this new one.

  What training classes are there for life?

  Not a whole lot unfortunately.
