Inert Conductors as Electrodes

In our course reader it says that platinum is the most common metal to be used as an electrode. Why is this so? After doing some research online it seems unclear as to if platinum or gold is more ductile. Is this simply a cost thing or does it have something to do with the metal having to be inert?

Because it is inert it is used to measure the Electrode potential of half-cells through a process named Standard Hydrogen Electrode. So its used to obtain those values we use for calculating the potential of the entire Redox Reactions.
