Fullerton police stop man pointing gun at female driver, only to learn he is ICE agent
A Fullerton police officer told the agent he couldn't help 'with someone following or recording him if no crime had occurred.' Under state law, local police cannot enforce federal immigration law.

The brain is an prediction machine. It guesses what will happen and updates future guesses based on experience. Every perception, emotion, & decision depends on these forecasts. Over time, predictions become expectations, and expectations define who we become.

Congrats! Dean Michael Lu transformed public health by his research that gave us what we now call "the life-course perspective -- the idea that birth outcomes reflect not only the nine months of pregnancy but the long arc of a woman’s life before it."

#CharacterMatters We have a crisis of moral character in the US. "Good character is the foundation of building trust. Good character is having steady and permanent dispositions to do what is right and to refrain from doing what is wrong." Virtue is the act of good character. Use downloadable image.

"A growing body of research suggests that behavior is not just a matter of willpower; it's the result of prediction. Our mental system constantly generates expectations about what will happen next, including what we ourselves are likely to do, think, or feel."

Why We Act Against Our Values and How to Change
You know better, yet you stay stuck in old patterns. Maybe the real issue isn’t willpower, but your mind’s predictions about who you are.
