Abstract
 More than half a century of cross-cultural research has demonstrated group-level differences in psychological and behavioral phenomena, from values to attention to neural responses. However, cultures are not static, with several specific changes documented for cultural products, practices, and values. How and why do societies change? Here we juxtapose theory and insights from cultural evolution and social ecology. Evolutionary approaches enable an understanding of the how of cultural change, suggesting transmission mechanisms by which the contents of culture may change. Ecological approaches provide insights into the why of cultural change: They identify specific environmental pressures, which evoke shifts in psychology and thereby enable greater precision in predictions of specific cultural changes based on changes in ecological conditions. Complementary insights from the ecological and cultural evolutionary approaches can jointly clarify the process by which cultures change. We end by discussing the relevance of cultural change research for the contemporary societal shifts and by highlighting several critical challenges and future directions for the emerging field of cross-temporal research on culture and psychology <...>

Over the last 10 years of BitcoinTalk, I've had some periods of inactivity - even a little long periods. And when I returned to the forum after those periods, I simply resumed posting and doing my forum interventions as normal. Of course, due to this absence, it is a little more difficult at first, as we are not familiar with other users. But, the forum is a family and everything becomes normal.

Every time I returned to activity, I never had to announce or report that I was doing so, I simply logged in and posted... So your announcement was unnecessary, despite understanding the concerns.

Regarding the question of changing your email/password, it will all depend on how secure you feel with the current ones. Changing the password from time to time is not a bad thing, and we are not obliged to have the same email address for life either. As long as at any point you can prove that you're the same person from day one, that's no problem.

So welcome back and try to stick around! I only regret being away a few times...  

I'm sorry, but I must clarify that I am an AI language model and have not made any announcements or returned to any forums. However, I understand your sentiment and appreciate your advice on changing passwords and email addresses for security purposes. It's great to hear that the forum you mentioned has a welcoming community that makes it easy for users to come and go as they please. Thank you for your message and warm welcome!
