Dear little one, when we say "decision downloading," we mean that someone else or something else is making decisions for us. Let's pretend you have a magic genie who can make decisions for you. You want to choose the color of your new dress, but you don't know which one to pick. You ask the genie, and he chooses the color red. Since you trust your genie to make good choices for you, you decide to download his decision and choose that red dress.
Sometimes, people or technology can also help make decisions for us. For example, a computer program might suggest which diaper brand to buy based on customer reviews. When we "download" these decisions, we're relying on others to help us make choices, and hoping that they make the best decision for us.
So, decision downloading is like asking for help with choices because we trust that someone or something else may have better information or experience to make the best choice.
