When the analysis was repeated with controlling for all other factors included in the study, results showed that people who were more intolerant tended to show lower persistence, lower flexibility and higher perseverance.

Persistence is the disposition to continue working toward the goals despite temporary frustration or challenges (e.g., “I usually continue working until I have completed the task”). Flexibility is the ability to adapt one’s behavior to unexpected changes of the situation or circumstances (e.g., “Changes in my plans make me nervous”; “I resist changes in my daily program”). Perseverance is the disposition to repeat a behavior despite changed circumstances, even when that behavior is not appropriate for the new situation and the inability to rethink previous decisions and change behavior accordingly.

Ok so a good next step here might be to see if we can physically change people's abilities in persistence, flexibility and perseverance. I'm really not that surprised that inflexibility with tasks would cross over with intolerance as they're practically synonyms for one another. I'd take a guess that you'd find higher rates of domestic violence for a similar reason - inflexible, intolerant, impatient.

The question I have is if you can devise methods for changing these things in people and if doing so also changes their racial and cultural attitudes because they learn to chill the fuck out. Bit worried that this is going to lead me to acknowledging hippie culture as a contributing factor in improvements in society.
