The Granny-standard,a golden rule whether one is capable in his/her field to reduce his/her knowledge and explain what one is doing, that even a Grandma understands. Major critic to this standard is the fact that a Grandma is positively biased toward the grandchild.
A better standard would be the UC-12 Standard ( UC-12: unknown child of 12 years with interest in gadget's and high tech social network related things). One should explain what one is doing for profession, to a group of unknown children with age of 12-13 years. Due to the fact that there is no family relation (its unbiased) and if the level is too high and without entertainment, they lose the interest and its boring. First test of the UC-12 Standard was the Tag der Forschung 2012 (Day of Science).
