  • yeah, there’s nothing to argue here. These are scientific definitions of the two terms. A positive feedback loop can be negative in terms of consequences, but it doesn’t change the fact that the loop is defined as a positive feedback loop.

    The words “positive” or “negative” in terms of the loop definition do not refer to “good” or “bad”, but rather the mathematical definitions of “additive/multiplicative” or “subtractive/divisive”. A positive feedback loop is an additive or multiplicative function whereby inputs increase outputs which increase inputs which increase outputs.

    A classic example is a snowball rolling down a hill that grows in size and gains speed. Whether or not the snowball grows big enough and rolls fast enough to annihilate the school at the bottom of the hill, it doesn’t change the fact that by definition the feedback loop that is generating a larger and larger and faster and faster snowball is defined as positive.

    An example of a negative feedback loop could be you getting sick. The input being viral or bacterial particles enter your body, the output is your body temperature increases, which kills the pathogens thereby decreasing the input. The decrease in pathogens then signals to your body that the infection is receding, and you body temperature returns to normal (decreased output). You healing from a sickness is a positive (good) thing, but the feedback loop that did it, is a negative one.


  • I agree completely but just so you know, it’s a positive feedback loop even if the outcome is negative.

    A positive feedback loop is one where the input creates an output that then increases the input further, which in turn further increases the output.

    A negative feedback loop is one where the input creates an output that then lessens the input, which in turn decreases the output.

    Shrinking middle class begets ignorance. Political forces capitalize on ignorance to misinform and manipulate the masses to elect people and enact policies that are not in their best interest. Doing so further erodes the middle class and decreases education, begetting further ignorance, misinformation, and political extremism. Positive feedback loop.

    (Sorry if this was pedantic but it reminded me of a very specific learning moment I had with an old science teacher of mine about this exact distinction)
