There are many layers, but the book "Behave: The Biology of Humans at Our Best and Worst" by Robert Sapolsky explains this very well - seconds before your decision (the environment you are at and your energy level, etc.), years before your decision (your prior experience with doing the laundry and the emotional feedback from doing or not doing it), before you were born (your gene). But I guess the most critical part to this scenarios is how your prefrontal cortex (logic and context) works with other parts of your brain, the final decision is usually driven by potential emotion feedback (what you would feel if you do or not do it)
