What do you thing the world would be like if a perfect lie detector was built?
If every job you did, you had to have been screened by a truth machine first?
If in court a truth machine was used?
What if this truth machine became commercially available in a portable version, so parents could check their kids? or couples could check each other?
Do you think people would manage to deceive it, by only saying part of the truth?
Would a machine like this (the portable version) be morally correct? Would the changes it causes be positive or negative?
