People often put off decisions, which may be due to self-control problems (leading to present bias), inertia, or the complexity of decision making (see choice overload). Various nudge tools, such as precommitment, can be used to help individuals overcome procrastination. Choice architects can also help by providing a limited time window for action (see scarcity) or a focus on satisficing (Johnson et al., 2012).
