No argument here, just my own take on adding ice (sorry if this is a re-hash).
In chemistry, the usual method of analyzing the composition of complex organic mixtures is to use a GC-MS (Gas Chromatograph-Mass Spectrometer). This computer-controlled device is essentially an oven into which the mixture is injected at a low temperature (close to ambient room temperature
22 C or 72 F). By room temperature, I refer to a normally controlled air conditioned room, not one subject to outside ambient influence.
The mixture enters a stream of inert gas (helium) and passes through a long coil (column as we call it) during which time the oven temperature is increased slowly. This causes the different compounds to change to gaseous form at different times based on their molecular weight (and other polarity factors). This effectively separates lighter molecules from heavier ones which travel more slowly through the column. A detector at the end of the column signals when each separated compound leaves the column, effectively separating them by noting their exit times.
In whisky tasting, the lighter aromatic compounds evaporate more quickly from the surface of the liquid. The reason complex whisky changes character over time is that the relative percentages of each of these organic aromatics is constantly changing dependent upon their volatility. As lighter aromatics evaporate and leave heavier compounds behind, the character of the nose changes.
Adding a small amount of ice to a whisky effectively retards evaporation of lighter compounds. This has several effects. One is that the rate of change of the "nose" would be expected to slow down. Since all compounds would be cooled the same degree, you might enjoy the more volatile components of the nose for a longer period of time. But the relative rate of evaporation and hence change in the nose would remain the same, spread out over a longer period of time.
The downside to using ice is that cooling the liquid also suppresses the taste on the palate by dulling the taste buds. I suggest that either method works. By using a proper glass (I prefer a cognac balloon with a small opening), volatile component evaporation is retarded thus allowing a lengthened nose development. On the other hand, if you allow the whisky to linger on the palate long enough for it to warm to body temperature, and assuming that the taste buds can recover from the constriction of the colder temperature, there is no reason not to use a very small amount of ice if you prefer. It might be preferred to use ice if you don't have a proper nosing glass, in fact, such as dramming in a bar with inadequate glassware. Ice could effectively be used to "close" the mouth of the glass to evaporation so the full nose can be appreciated.
However, in my own home with my own glassware, I pour whisky at 22 C / 72 F, and add several drops of water from time to time to open the nose and allow the whisky to develop at "room temperature."
