Objective. To understand why a wide range of states of mind are expressed b
y spilling tears.
Methods: 465 different episodes of crying with tears were analyzed and thei
r motivation interpreted in the search for a common factor.
Results. The only common factor in all tear-spilling episodes was a relatio
nship with help: either requesting help or offering help. This leads us to
speculate on the biological origins of emotional tearing.
Conclusions. 1) The classical division of emotional tearing as either negat
ive or positive is based on accidental characteristics and does not answer
most of the questions. All kinds of emotional tearing are related to help,
and can be classified as requiring-help and offering-help. 2) Why do we spi
ll tears when we are asking for help? When children need help because of hu
nger, fear or pain, they add tearing to sound and body language to symbolis
e their suffering. Accordingly, tearing was chosen as a symbol of suffering
because the reaction was already present as a reflex response to physical
pain when ocular trauma and inflammation occurred, as they did very frequen
tly in mankind's past. Moreover, this sign is seen on the face, the most co
nspicuous part of the body. 3) Why do we spill fears when we are offering h
elp? As humanity evolved and needed to express empathy and sympathy, ie. an
emotion diametrically opposed to requesting help, the same core symbol was
used, though the facial and body language are different.
