A Mind Trap (see also, Jedi Mind Trick) is a picture of the world that is self-reinforcing. Once inside the mind trap, everything you see will be confirmation that the picture is correct. The mind trapper usually attaches some strings to the trap so that you give them money or follow their commands.
So how do you tell whether someone is trapping you or telling you something real about the world?
When someone tells you something real about the world, they are making a prediction of some kind. For example, if someone tells you that it is less expensive to give people prescription drugs than it is to pay for the consequences of not doing so, they're making a testable prediction.
However, if they tell you God exists, and you should act in certain prescribed ways, but that nothing you ever see will ever be in contradiction with their holy book, well... reach for your light saber! The messenger is either stuck in the trap or is the trapsetter him/herself.
Evidence cannot point to a conclusion when that conclusion does not predict the evidence. Being consistent with the evidence isn't enough for inference.
A lot of people don't understand this. This is why there are numerous mutually-exclusive belief systems that make no predictions, and why believers in such systems always see the evidence (indeed, all things) as confirming their beliefs. Once inside the trap, believers often give up their critical thinking, outsource their ethical analysis, pay the trapsetter large sums of cash, and in the worst case scenario, do harm to others.
Believing in pictures of the world that make no predictions is the surest way to self-delusion.
By the way, Intelligent Design also "predicts" whatever you observe, no matter what you observe. It, too, is a mental trap. Accept its premise and you'll see designed stuff everywhere, but nothing you ever see will be inconsistent with Intelligent Design.
