Feedback can change our behavior. If I put my fingers on something hot and burn them, I get immediate feedback in the form of pain; causing me to jerk my hand back. I remember not to touch that thing again! A fast and strong feedback loop causes behavior change.
A slow feedback loop is not as effective in motivating us. The danger of HIV/AIDS is that it can take years for the disease to have its first noticeable negative effects. The same is true of a poor diet. It takes information and discipline to make changes in our lives for things that have slow feedback loops. So we have to know the dangers of high blood pressure, for example, and take our blood pressure (information), then we have to have the discipline to change our diet and/or take medication to keep it under control.
Missions – the effort to make Jesus known everywhere – suffers from a similar problem. An evangelistic campaign with a big public meeting might result in many people accepting Christ. That is quick and positive feedback. Reporting those numbers will motivate Christians to give to the evangelist. But research shows that the number of those who continue in their faith can be quite low. That information is part of a slow feedback loop, so it tends to have less impact on Christians who are deciding where to send their mission dollars. Like slow feedback in health issues, for slow feedback in missions to affect how Christians give to missions, there is a need for information and discipline.
German missionaries first translated the Bible into languages of Ghana. Johan Christaller’s translation of the Bible into the Twi language was published in 1871. Translations of into other languages in the south and central parts of Ghana were completed in the early 20th century. Over the next 100 years, many Ghanaians became Christians through the use of those translations. Large and solid churches were established. 100 years is a really slow feedback loop. The organization Dayle and I are on loan to, GILLBT, published its first New Testament in a language of Ghana much later – in 1976. It published Scripture in a number languages over the 1970s, 80s and 90s. Around 2000, some Ghanaians started studying the impact these translations were having. The results are quite remarkable. I have blogged about them and spoken in churches about them, so I won’t repeat them here.
Think about the slowness of that feedback loop.

Dr. Sule-Saa’s doctoral thesis which explored the impact of the translation of the Bible in two languages of northern Ghana
The research to show the effectiveness of the translation appeared 36 years after the translation started. The translators must have worked in faith that the translation would have an impact. They probably had some stories of impact the translation was having on some people, but they could not know if the effort was going to effective until it was done. In fact, not until years after that! (We are hoping to speed that loop up in the future, but it will still be relatively slow.) A friend of mine who has done quite a bit of research on the impact of Bible translations in Africa says that the biggest impact of translations start about 10 years after they are published.
But the feedback loop is even slower than that. The translation done in 1976 continues to have impact even after the research about its impact was completed in 1998. We know that from anecdotal information. But we don’t know when that impact will be formally evaluated again. It is probable that the feedback loop on many translations will be so long that those who did the translation and all who supported it through prayer and finances will have left this world before all the feedback is known, if it ever is.
Any mission work that has sustained impact over decades will have a very long and slow feedback loop.
I am working on a project with a church in northern Ghana that builds the methods proven effective in the long-term to reach out to the two least evangelized peoples of Ghana with a total population approaching 1.5 million. That really makes me excited, even though we may not see significant results for another 3-5 years.
Some people may give to missions and Christian ministries when there is a dramatic and quick feedback loop, but not much otherwise. That kind of giving is good for emergencies and disasters, but it doesn’t work well to produce sustained impact. For that, regular and well-targeted giving is better.
