Answer: Practising empathy
Explanation: Empathy basically means having a number of different experiences, which translated into reality means being able to feel or see how someone else feels. This is certainly one way of increasing tolerance in culturally diverse environments, groups, organisations, companies, because when we know how he or she feels or why he or she thinks, we can more easily understand his or her aspirations and actions and will not take it as a threat to our positions and interest, therefore, we will not be intolerant.
There is an opinion that empathy should be practised and thus promoted, above all, by directing mutual focus and strengthening such focus, while avoiding one-way focus that may be detrimental to developing good relationships in a culturally diverse group, environment, etc.
In addition, useful ways to practice and enhance empathy are to share your feelings with others, to recognise and invest effort in recognising how others feel, to show appreciation for others' openness, to be supportive, and so on.
