The bug
When you right click with a carrot on a stick it always increases the usage statistic value for it even if you did not really use it.
I know that this is a technique used by map makers, but it would be better to have a generic way to detect right clicks than to rely on situations like this.
How to reproduce
Add an objective with the
minecraft.used:minecraft.carrot_on_a_stickcriteria, set it to display on your sidebar, and set your score to 0 so it displays/scoreboard objectives add carrotOnAStick minecraft.used:minecraft.carrot_on_a_stick /scoreboard objectives setdisplay sidebar carrotOnAStick /scoreboard players set @s carrotOnAStick 0Right click with a carrot on a stick while not riding a pig
Code analysis
Based on 1.11.2 decompiled using MCP 9.35 rc1
The method net.minecraft.item.ItemCarrotOnAStick.onItemRightClick(World, EntityPlayer, EnumHand) always increases the usage statistic value.

No, it tracks how often you perform the item's use. stat.useItem.minecraft.stick is never incremented. Items with different uses increment at different times. For example – throwing a snowball, eating a porkchop, attacking with a sword, planting seeds. Simply right-clicking with the seeds won't increment the stat unless they were planted.
I'd like to point out that this issue creates a gateway for custom active items to be implemented in maps. Carrot on a stick can be used as a "unversral right click detector", and paired with a resource pack durability predecate for textures, to generate up to 26 custom items - or even more if negative durability values are used.
The rare case of having to detect a pig speed boosted with a carrot on a stick over unmodded custom items, this is a tough choice indeed
The statistic stat.useItem tracks how many times you use the "use" key while holding an item. For example, if you do /scoreboard objectives add Stick stat.useItem.minecraft.stick it will tell you how many times you right clicked with a stick in your hand.
