First you'd have to identify a scientific method in regards to how forces can be applied to receptors to make them "understand" a signal, in regards to Telekinesis it's not just about the very low level manipulation but generating a force that can either be greater or match the mass of an object or can effect the masses natural frequency ranges.
A good simple example of how I mean is having two Bells near one another, when is struck it generates reverberation throughout all molecules within the distance that the sound travels. Depending on the proximity of the other bell defines as to whether the other bell actually "Harmonically" rings with its counterpart.
The fact is with this example though is there is Physics involved in making that bell ring, it doesn't just magically start ringing it needs a "Medium" (No I don't mean one of those people that thinks they know your magic numbers or speaks to the dead, I mean a physical bridge between one action and another)
An example of a Human aspiring to do Telekinesis is this:
You rig monitoring devices to either a persons brain or just their pulse, The device is then connected to a hammer system over the first bell that was mentioned. Should they have a specific thought pattern or just raise their pulse (thinking of an attractive member of the opposite sex for most Hetrosexual's is enough to get a reaction here) then the hammer should ring the bell. The sound should then travel and reach another bell which will start to "ring".
Obviously though this is Apparatus drive, I really don't think it would ever be naturally possible at least not further than a few neuron clusters. (All life and even electricity gives out a radius of electromagnetic flux, this flux could be interpreted like the ringing of the first bell in the example, it's then just about creating something capable of being able to receive the information and convert it into an action. The point here is that EM level is a low output and doesn't have much of a distance before it either dissipates or is swamped by background noise)
So simple Answer to your Norsefire, It can only practically be done "Artificially" and without the Artificial Medium it's too limited to be of use.
