Just as you have ignored the contemporary examples of Japan and Argentina. Japan has practically zero interest rates and no accelerating inflation (contrary to the beliefs of the interest rate obsessed), whereas Argentina has massive interest rates and rampant inflation.
As for Turkey, you can't just put the interest rate down. You have to suppress luxury imports to give up import space for needed imports, start taxing effectively to drain excess Lira from the system and then look at the Lira banking policies and the firm insolvency rules so they stop making things worse.
And, yes, the idea of making the currency go down, and suppressing luxury imports to control the price of needed imports is so that 'abroad' will invest in Turkish firms, bringing in the 'patient' money that can eliminate the 'hot' money of foreign currency loans that need regular servicing. A debt for equity swap in other words.
However in Turkey's case Erdogan is still fully signed up to 'export led growth' neoliberalism. He just has a religious problem with interest. So he's not adopting any alternative economic strategy at all.
As to the Taylor rule, nobody follows it - because it is mathematical bunkum.
The best explanation of how the Taylor rule works in the standard NK model is in the PHD macro II lecture notes of Eric Sims. Eric Sims is a highly respected mainstream macroeconomist, and his lecture notes have often been recommended to me as the best source of knowledge on how the NK model works. These notes are from a PHD macro II class he teaches.
According to Eric Sims when Taylor originally proposed the Taylor rule he thought it would control inflation in the following way. In his view, peoples’ propensity to consume is based on the real interest rate. In order to reduce inflation the central bank must reduce consumption, and it does so by raising the real interest rate. To do so it must raise the nominal interest rate by more than the increase in inflation, since the nominal interest rate is approximately equal to the real interest rate plus the inflation rate.
However, Sims states that Taylor’s original intuition is not how the Taylor rule works in the standard NK model. Instead, the central bank uses the Taylor principle to rule out indeterminacy by creating explosive inflation dynamics. If inflation gets above target the central bank increases inflation further, ensuring that the inflation rate eventually goes to infinity. Somehow solutions with infinite inflation in inflation are ruled out, and so by destabilising the economy the central bank ensures inflation will stay on target.
