      This is one of the problems with applying cybernetics to human behavior like you would with psychology. It's not really the right tool for the job, nor is it meant to be - it's about describing and understanding systems.

  Every minus sign inverts the direction of the change. Every plus sign leaves the direction of the change as it is. More doing things leads (+) to more feeling good, which leads (-) to less depression, which leads (-) to less de-motivation. But more de-motivation leads (+) to more depression, which leads (-) to less feeling good, which leads (-) to more depression.

    A fair number of systems created here haven't grokked the behavior of (-), leading to models that don't actually behave as intended. I admit, it took me a few tries to notice, myself. The description given for relationships doesn't help, suggesting that (-) does nothing more than changing 🡩 to 🡫. Having three options, more (🡩), less (🡫), and flip (↕) would have been clearer and more versatile.

  I can't find a good solution for the problem and that's a bit depressing... This feels a bit more accurate to me though: http://bit.ly/2nsIOXc http://bit.ly/2nsIOXc
