I have come across the phenomenon in my community. Many organizations are looking for new people to become members. They are made welcome and people appear to be friendly.
When it comes to the rituals or events organizers are reluctant to change their ways to help people learn and be comfortable in their new environments.
In many churches it is assumed that anybody walking through the door knows "The Lord's prayer". This is not the case.
In sporting events it is assumed that you know something about the sport before you begin. This is not the case.
I belong to a number of organizations who automatically assume that you know everything about an event that is going on. When you ask questions you are made to feel foolish by not knowing about past events and how they are run.
It is important for all organizations to reduce the amount of embarrassment of a new member.
Through strategic planning of an event as many details and timetables explaining how the event is run, should be listed. There should be little surprises and all members should be comfortable in participating in this event. Assume that every member is a new member and the first time playing. Using this philosophy questions will be gone people will feel more comfortable and look forward to the participation because they know what is coming.
Above all reduce embarrassment. When people ask questions answered them sincerely, with understanding.
Provide mentors or buddies wherever possible. Even if a member has been active for many years pair them up with someone whose run that event before.
Remember the world is full or skeptics and criticism. Help reduce this by standing behind and give them support.
