Sometimes the filtering is fine  It makes it easier to see similarities and patterns. However, sometimes we make assumptions, like white is snow.  Sometimes we filter too much.

Quick  What is 2 + 8?

If you answered 10, that is a System 1 - Jump to conclusion, type of thinking.

System 2 type of thinking would have you asking for the context.

It takes energy to do critical thinking, but looking for alternative answers can be fun.

1 cup     8 fl. oz.   >  250 ml milk = 2.5 x 103 g =         257.5 g

1T cocoa = 7.38 g   >   2 T cocoa - 2.0 x 7.38 g =   + 14.76 g

                                                                                   272.26 g chocolate milk (hot cocoa)  *Weight of mass would vary slightly depending on where you are located.                                           

* "You would weigh very slightly more at sea level than at the top of a mountain, not enough for you to notice, but a measurable amount." according to https://www.physlink.com/Education/AskExperts/ae111.cfm

This does not take into account the vapor pressure, air pressure, or ratio of the number of particles of solute and solvent in the solution.  More on colligative properties at https://chemed.chem.purdue.edu/genchem/topicreview/bp/ch15/colligative.php  and https://www.le.ac.uk/se/centres/sci/selfstudy/particle05.html

….understand the context before jumping to conclusions.
