“You may think that you control most of your choices, but the truth is that a large portion of your actions every day are simply a response to the environment around you. The forms you are mailed, the food on your kitchen counter, the items on your desk at work — they all impact your behavior in one way or another.

Bringing it back to the researcher’s quote, we could say that your environment is the “default option to which you are assigned.” The environment you surround yourself with determines the default actions that you take on a day–to–day basis.”
