Show me the trust
Everyone is happier and more productive when they are trusted. It encourages co-operation between people and organisations. We like museums that let us stand near the artwork, police that don't stop and search us, restaurants that give us the bill at the end of the meal. But some companies cannot rely on trust and genuine good intentions. Banks must behave as is every transaction is a fraudulent one - it annoys us when our cards are stopped because of "unusual spending" but the banks know that people do get scammed and they behave accordingly. That trust / don't trust decision is something we all face every day. We automatically make assumptions about whether promises will be broken, how trustworthy a supplier is, how reliable the service will be. In every sector (apart from banking) it is probably better to trust than not to. You are more likely to get the result you need.
