This site http://wordnetweb.princeton.edu/perl/webwn?s=superstition provides the following definition for "superstition": an irrational belief arising from ignorance or fear
That describes the whole WTS/JW theology, doesn't it? They have irrational beliefs, such as:
- Jesus invisibly returned in 1914
- Jesus selected the WT Society as his faithful slave in 1919
- Despite documented failed predictions of The End in 1914, 1918, 1925, and 'a generation after 1914,' the WTS is not a false prophet
- Most of Revelation was fulfilled in the early 20th century by Rutherford and his associates
- Only active JWs have any scriptural hope of surviving The End, which is coming "imminently," even though there are BILLIONS of people who have never heard of the JW faith
And these beliefs are necessarily based on ignorance--because there's no proof for them. For example, the Society cannot prove that Jesus "returned invisibly" in 1914--it was invisible! Kinda like the Emperor's New Clothes...
Finally, fear comes into play. Fear of death, fear of being ostracized from friends and family.
