This month on the Sighten blog, we're kicking off a blog series exploring several key principles in the science of decision-making. Using some simple yet powerful concepts, you'll be able to make sure your solar sales process maps to how the human brain actually processes information and makes buying decisions.Adopting these data-driven strategies will help you develop effective, repeatable ways to close more deals. We'll also show you how MyProposal, Sighten's solar proposal tool, makes it easy to incorporate these insights into your sales process.This post will focus on two separate but related concepts: single option aversion and the decoy effect (also known as the asymmetric dominance effect). While the scientific jargon can make these seem like complicated concepts, they're actually fairly intuitive.
