The greatest and most important concept that I will take away from Psy 1001 is that there are no certainties in anything. The world of Psychology and our world in general is full of gray area. Its not simply nature or nurture, its the intricate balance between nature and nurture. There is no one specific chemical balance in the brain that causes a disorder, nor is it one specific event.
What this has all taught me is that there is rarely a right or wrong answer in life. There is never one specific cause to something happening. There is no one sure answer to the questions and challenges we face, which might not seem reassuring, but it makes life that much more curious and beautiful.
