Insights that could change our lives

When facing a problem we tend to generalize so we can approach the problem at a systemic level. We do this when building products but also in how we conduct our lives. However, it's mostly premature:

• Abstraction is a form of optimization and should not be done before the space has been properly explored. 
• Standardization is also optimization and should be avoided until there is enough evidence to support the standardization. 

A leading question inquires about whether the other person agrees or not with a statement. Interrogative ones start with what, why, when, who, where. 

"Did you like the song?" (leading) vs "What did you think about the song?" (interrogative). 

A leading question is more emotionally charged and low in information. It leads to .... worse engagements.
