Humans trust by default

Long term uptrends are created and managed by:

1. Flooding the economy with money
2. Fed works most with primary dealers who are most certain to funnel funds into the equity market
3. Controlling news delivery and content
4. Regulators ignore market manipulation that causes higher prices

Never forget that Wall Street is above the the law. The higher up they are the more they are above the law.

Robots are profitable to the degree they can create and manage uptrends in time periods ranging from seconds to months. Robots take losses in downtrends. Each robot is a detriment to every other robot. There are too many robots in operation now for any one to make much or any profit.
