Testing negative for a particular talent may be inferred as the child not being naturally-inclined in the particular field. Therefore if the child wishes to excel in the area, he/she will have to make up for it through sheer hard work and possibly also some environmental factors and favorable fortune.
For example, if a child does not possess the gene for good memory, he/she may not do as well in studies, especially in the subjects which require considerable memorization and rote learning. Therefore to perform as well as a kid who is naturally gifted in this area, the child who is not naturally-endowed will have to put in a lot more effort and time into studying. It may therefore not be very efficient if parents force this child to take the academic major that requires great memory power as he/she may not be able to perform as well as other children even after putting in a lot of effort. It may then result in a loss of confidence and esteem.
