Can hot peppers make sweet peppers hot

[PureHarvest]

Sorry if this topic was discussed in the past. The search feature frustrates me here.

Basically I have read elsewhere lots of comments arguing both sides whether or not a hot pepper can make a sweet pepper taste hot in this year's fruit (not next year's accidental F1 being grown out and resulting in a hot bell for example.)

I know field corn can pollinate a sweet corn and this year's harvest won't be sweet, so...
What do you say?
