When people describe neutrino interactions they describe them as rare/infrequent due to the fact that the neutrinos are electrically neutral and have little mass, if any. Well why then is the photon much more strongly interactive considering that it is neutral and massless? What is the discrepancy between the two? Why is the neutrino so elusive, whereas light is so prevalent? Does this perhaps have anything to do with the fact that a neutrino is a fermion whereas a photon is a boson?
The photon does couple directly to charged stuff, e.g. via Compton scattering. This is indirectly related to the spin, as direct interactions between fermions are hard to construct.
The neutrino on the other hand does not couple immediately to any other matter particle. It requires a force-carrier. Now as it turns out the only force carriers that care about the neutrino are the $W^\pm$ (and to lesser extent the $Z^0$ boson). These are really really massive, however, making the interaction very rare.
This is a different situation than for an electron, for example. It also does not couple directly to other matter particles. Still, it can interact via the photon, which is massless and can therefore easily transmit energy and momentum.
Neutrinos having no charge means they don't participate in electromagnetic interactions, which are the strongest (at least long range). Them being leptons means they don't interact with the strong force (which is, as the name says, strong), hence they can only interact via the weak force, which is, as the name says, weak.
Photons on the other hand do not carry charge, but they transmit electromagnetic energy, hence they in fact DO participate in electromagnetic interactions (oscillating electric circuits radiate). Why is that? The photon is in fact (in a sense) the agent that transmits electromagnetic force between other particles; it is the gauge boson of the electromagnetic field. Almost all elementary bosons in the standard model (except the Higgs) are in fact gauge bosons, i.e. they are the force carriers of some of the elementary forces (strong, weak, electromagnetic). Therefore, they all have to interact quite strongly in some sense.
All in all, this means that yes, the two are very different and it has something to do with the fact that the photon is a boson and the neutrino is a fermion, but on a different level than you might think.
We know four fundamental forces, three of them being included in the Standard Model. At low energies (compared to the mass of $W^\pm$) the forces have strengths as follows:
strong force > EM force > weak force > gravity
Also, photon and neutrino are really quite different. Photon is a force carrier, while neutrino is a matter particle.
Now, matter particles only interact if they carry the relevant charge. The neutrino only carries weak charge, and can therefore only interact via the weak force. The photon is the carrier of the EM force.
Now, the above inequality says that the EM force is stronger , which means that the photon interacts more often than a neutrino.
