Should I use `!IsGood` or `IsGood == false`?

language-agnostic

I keep seeing code that does checks like this

if (IsGood == false)
{
   DoSomething();
}

or this

if (IsGood == true)
{
   DoSomething();
}

I hate this syntax, and always use the following syntax.

if (IsGood)
{
   DoSomething();
}

or

if (!IsGood)
{
   DoSomething();
}

Is there any reason to use '== true' or '== false'?

Is it a readability thing? Do people just not understand Boolean variables?

Also, is there any performance difference between the two?
