This is a quite new method which was established by Dorian Schmidt. The method is  not yet validated according to scientific criteria. However, it is supposable that this is possible, similar to the sensory analyses.

Methodology
Applying this method, man becomes an instrument, which is similar in sensory analyses. The point is to measure the effect on the own liveliness. ... By appropriate training of the attentiveness, very differentiated effects of food can be perceived.

Each healthy person basically possesses these ability to observe. After a short phase of accommodation, considerable differences can be discovered, in the effects of for example of carrots or potatoes on us. After some hours of introduction, it should be possible to distinguish between organic and conventional food. The reason why this method has such a high potential, is that each person can become an expert in assessing food.

In contrast to sensory analyses – which trains the degustation – the research on formative forces is about the training of the alertness for the own body and the own liveliness. This ability is in typically poorly developed...

In detail it is about the training of the thinking, feeling and wanting. Not until we are aware of these, we can purposefully use them to observe the own liveliness and the effects of food on them.

By means of easy, short exercises laymen can be shown that fine activities permanently take place within us, which we generally ignore as we do not concentrate our attention on them. Examples for such exercises are among others: which effects do the feelings A and  B , in which we put ourselves, have on us. Or from the field of thinking: Try for some time to think of nothing. What happens? Where does a perception occur? And from the field of wanting, e.g.:  What can we observe, if we simultaneously try to carry out movements of different rhythms.

How do the different events of observation occur? Forces can be felt, which take forms and are able to move. Apart from the feeling/sensation of the forces in the body, with advanced practice or capability, a pictorial perception simultaneously occurs. Therein, the peculiar observation that perceptions do not end at the borders of the physical body can be made. ...

Since several years, the presented method is successfully applied in biodynamic research for very different questions. Well grounded and experienced observers obtain more exact results than it is possible with other known methods. The results point in general in the same direction as those of e.g. picture-forming methods, but are more precise.
