@Emilia42 That is a good question. Here is my thinking. The review process has been evolving. After reading the posts in this forum, you can easily see that there are various ways that hosts try to “educate” or provide hints to guests in order to get 5 stars rating.
At least that is how I did when I received new guests. Once a host has star ratings established, the future guests read the reviews, they tend to give high ratings as well. That is why Airbnb ratings are highly inflated in many cases.
The first screenshot in the review most likely was introduced later. Back two years ago before I was a host, when I used Airbnb a couple of time, I did not see the first screen with those options. At that time, I remember that I could see star ratings given by hosts as well after both reviews were published.
The other thing to note is that majority of hosts care the ratings a lot. They do make lots of effort and do their best to accommodate guests. And personal interactions between hosts and guests also help the high ratings. Airbnb started with hosts letting out their spare rooms. That created opportunities to have personal interactions between a host and a guest.
i am not trained in psychology. These could be explored as a topic in psychology and behavioral research. You have more hosting experience than I do. You may have much more findings and batter understanding than I do. Thanks for the questions.
