I was born in, and in for nearly 6 decades. My critical Thinking skills were close to Nil. But, I had ever since I was very young, a thirst for knowledge, which I still have. I always read a lot. Still do.
But most of my J.W contemporaries were downright lazy, they read little, and thought less, I think the ones who read a fair bit and thought a bit, nearly all left before me. In fact one Elder said to me " We are losing all the intelligent ones", which made me wonder, but not quite enough at that time.
I think the ones who have left in the last few years are often of the " Lazy Class" LOL, so used to having been spoon fed what they should read and think, that they have lazy reading habits, and nil Critical Thinking skills. You can see that by the comments they make on here , and the questions they ask. of course there are exceptions to this generalisation.
It does take a little effort to read enough, and then you need to Fact Check what you have read, google etc can often be false friends.
But it is such a joy to be able to spot bullshit straight away, or at least in a short time of Fact Checking, such a joy to round out your knowledge, and a joy to not be misled.
The Lazy Class are not using their freedom as they should, and are missing out on becoming what they should.
